Description

Technical Field

[0001] This invention relates to the field of battery swapping technology for new energy construction equipment, and in particular to a mobile battery swapping device for tunnel construction machinery. Background Technology

[0002] In tunnel construction, traditional fuel-powered construction equipment faces significant limitations in the confined environment of tunnels due to issues such as exhaust emissions and noise pollution. New energy construction equipment, with its zero emissions and low noise, has become an ideal choice for tunnel construction. However, new energy construction equipment faces the challenge of limited battery life when operating continuously inside tunnels, especially in long-distance tunnel construction. In such cases, the equipment needs to perform battery replacement or charging inside the tunnel to ensure the continuity and efficiency of construction operations.

[0003] Currently, battery replenishment for new energy construction equipment mainly relies on fixed charging facilities or hoisted battery swapping. While fixed charging facilities can provide a stable power supply, the long charging time significantly impacts construction efficiency. Hoisted battery swapping, although enabling rapid battery module replacement, faces severe space constraints when used inside tunnels. The clearance height inside tunnels is typically limited, failing to provide sufficient operating space for hoisting equipment. This is especially true in construction environments with strictly limited clearance, such as shield tunnels and mine roadways, where traditional hoisted battery swapping equipment simply cannot enter or operate normally. Furthermore, tunnels typically contain ventilation ducts, lighting facilities, monitoring equipment, and other ancillary facilities, further reducing available vertical space, making hoisted battery swapping, which relies on vertical lifting, unsuitable for the battery swapping needs within tunnels. Existing manual handling and replacement methods, while not subject to clearance restrictions, suffer from high labor intensity, high safety risks, and low operational efficiency, and lack automation, failing to meet the efficiency requirements of modern tunnel construction. Summary of the Invention

[0004] The main objective of this invention is to propose a mobile battery swapping device for tunnel construction machinery, aiming to provide a device that can adapt to the limited clearance environment inside tunnels and realize automated battery swapping operations.

[0005] To achieve the above objectives, the present invention proposes a mobile battery swapping device for tunnel construction machinery, wherein the tunnel construction machinery is new energy construction equipment, and the new energy construction equipment extends along the X direction; the mobile battery swapping device for tunnel construction machinery includes: A mobile mechanism, which extends along the Y direction and is disposed on one side of the new energy construction equipment; A modular energy storage structure, wherein the modular energy storage structure can be detachably connected to the power supply end of the new energy construction equipment; A battery swapping mechanism is disposed on the moving mechanism. The battery swapping mechanism extends along the Y direction and can be raised to a receiving position or lowered to a discharging position. The battery swapping mechanism can also extend along the Y direction to an extended position or retract to an initial position. Specifically, when the battery swapping mechanism is positioned at the receiving position and in the initial position, the battery swapping mechanism extends to the extended position and connects with the modular energy storage structure before retracting, thereby driving the modular energy storage structure to slide along the Y direction to the initial position and charge it, and then driving the modular energy storage structure to descend to the discharge position; or, when the battery swapping mechanism is positioned at the discharge position and in the initial position, the battery swapping mechanism connects with the modular energy storage structure, extends to the extended position, and resets to the initial position, thereby driving the modular energy storage structure to slide along the Y direction to the extended position and connect electrically with the power supply end of the new energy construction equipment.

[0006] In one embodiment, the moving mechanism includes an integral frame and a loading plate, both of which extend along the Y direction, and the battery swapping mechanism is mounted on the loading plate.

[0007] In one embodiment, the new energy construction equipment includes a chassis, a support platform, and a socket. The chassis extends along the X direction, the support platform extends along the Y direction, the support platform is mounted on the chassis, the battery swapping mechanism is located on one side of the chassis corresponding to the position of the support platform, the socket is mounted on the end of the support platform away from the chassis, the socket forms the power supply end of the new energy construction equipment, and the modular energy storage structure is detachably plugged into the socket along the Y direction and electrically connected to the socket.

[0008] In one embodiment, the new energy construction equipment further includes a locking mechanism. An installation space is provided between the upper frame and the bearing platform. The locking mechanism is housed in the installation space. The connecting end of the locking mechanism is installed on the upper frame.

The free end of the first lifting drive component is used to drive the connecting plate to rise, thereby causing the connecting plate to press against the bottom of the bearing platform, so that the locking plate extends upward above the bearing platform, and the locking plate is in the locked position to press against one side of the modular energy storage structure on the new energy construction equipment. Alternatively, it can be used to drive the connecting plate to descend, thereby causing the connecting plate to move downward away from the bottom of the bearing platform, so that the locking plate retracts downward below the bearing platform, and the locking plate is in the reset position to disengage from one side of the modular energy storage structure on the new energy construction equipment.

[0010] In one embodiment, the battery swapping mechanism includes a bracket, a support plate, a column, a multi-section telescopic rod, a second lifting drive component, a charging base, and a connecting structure. The bracket extends along the Y direction and includes a receiving section and a discharging section, with the receiving section spaced above the discharging section. The support plate extends in the same direction as the bracket and is spaced on one side of the bracket. The column extends vertically, and both the column and the charging base are connected to the end of the support plate away from the bracket. The connecting end of the multi-section telescopic rod is connected to the top of the column. The free end of the multi-section telescopic rod is connected to the connecting structure. The free end of the multi-section telescopic rod can extend along the Y direction to the extended position or retract to the initial position. The connecting structure can descend to the abutment position or rise to the release position. The free end of the second lifting drive is connected to the bearing plate. The second lifting drive is used to drive the bearing plate, the column, the multi-section telescopic rod, and the connecting structure to rise to the receiving position or descend to the discharge position. When the bearing plate is set in the receiving position and the free end of the multi-section telescopic rod is in the initial position... When in position, the free end of the multi-section telescopic rod is extended to the extended position to move the connecting structure to the side of the modular energy storage structure away from the support. The connecting structure descends to the abutting position and abuts against the modular energy storage structure. The free end of the multi-section telescopic rod retracts to the initial position, so that the modular energy storage structure is pulled along the support through the receiving section to the initial position and detachably connected to the charging base, charging the modular energy storage structure. Then, the second lifting drive component drives the modular energy storage structure... The structure descends to the discharge position, and the connecting structure rises to the release position; or, when the bearing plate is positioned at the discharge position and the free end of the multi-section telescopic rod is in the initial position, the connecting structure descends to the abutment position and abuts against the side of the modular energy storage structure away from the support.

[0011] In one embodiment, the connection structure includes a mounting plate, a third lifting drive component, and a connecting piece. The mounting plate is mounted on the free end of the multi-section telescopic rod, the connecting piece extends vertically, the connecting end of the third lifting drive component is mounted on the mounting plate, the free end of the third lifting drive component is connected to the connecting piece, and the third lifting drive component is used to drive the connecting piece to descend to the abutment position or rise to the release position.

[0012] In one embodiment, the charging base has a charging port on the side facing the bracket, the modular energy storage structure is detachably plugged into the charging port along the Y direction, and the charging port is electrically connected to the modular energy storage structure.

[0013] In one embodiment, the modular energy storage structure includes a frame and an energy storage structure. The frame is disposed outside the energy storage structure. The extension directions of both the frame and the energy storage structure are consistent with the extension direction of the support. The frame is disposed outside the energy storage structure. Both ends of the energy storage structure along its extension direction are provided with plugs. One of the plugs is used to electrically connect to the power supply end of the new energy construction equipment, and the other plug is used to electrically connect to the charging base.

[0014] In one embodiment, the support includes a bottom track, a top track, and multiple uprights. The multiple uprights are arranged at rectangular intervals along the Y direction. Both the top track and the bottom track extend along the Y direction and are located on one side of the new energy construction equipment. The top track is spaced above the bottom track, and the end of the top track facing away from the new energy construction equipment is hinged to the upright. The top track is inclined downward from the upright towards the new energy construction equipment. The top track forms the receiving section, and the bottom track forms the discharge section. The bottom end of the top track abuts against the bottom track. On the track; when the battery swapping mechanism is set at the discharge position and in the initial position, the battery swapping mechanism is used to connect with the modular energy storage structure, extend to the extended position and reset to the initial position, so that the top track is abutted by the top of the battery swapping mechanism and rotates upward, so as to drive the modular energy storage structure to slide along the support through the discharge section to the extended position and be electrically connected to the power supply end of the new energy construction equipment. A buffer pad is provided at one end of the top track that abuts against the bottom track; a slider adapted to the top track or the bottom track is provided at the bottom of the frame, and the slider is slidably connected to the top track or the bottom track.

[0015] The technical solution of this invention achieves automated battery swapping of modular energy storage structures in confined spaces within tunnels by combining the horizontal movement of the moving mechanism along the Y-direction with the telescopic and lifting motion of the battery swapping mechanism. By using a horizontal push-pull battery swapping method instead of the traditional vertical hoisting method, it completely avoids dependence on the tunnel's clearance height and can operate normally in narrow tunnel environments with ventilation ducts, lighting facilities, and other ancillary facilities, effectively solving the technical problem of traditional hoisting battery swapping equipment being unable to enter or having limited operation. Furthermore, the battery swapping mechanism, through lifting to different positions combined with telescopic motion, can automatically complete the entire process of grabbing, charging, and installing the modular energy storage structure without manual intervention or complex mechanical adjustments, significantly reducing operational risks and labor intensity, and improving battery swapping efficiency. Through the detachable electrical connection between the modular energy storage structure and the power supply end, rapid battery replacement is achieved, avoiding construction interruptions caused by prolonged charging and ensuring continuous and efficient operation of new energy construction equipment within tunnels.

[0023] In tunnel construction, traditional fuel-powered construction equipment faces significant limitations in the confined environment of tunnels due to issues such as exhaust emissions and noise pollution. New energy construction equipment, with its zero emissions and low noise, has become an ideal choice for tunnel construction. However, new energy construction equipment faces the challenge of limited battery life when operating continuously inside tunnels, especially in long-distance tunnel construction. In such cases, the equipment needs to perform battery replacement or charging inside the tunnel to ensure the continuity and efficiency of construction operations.

[0024] Currently, battery replenishment for new energy construction equipment mainly relies on fixed charging facilities or hoisted battery swapping. While fixed charging facilities can provide a stable power supply, the long charging time significantly impacts construction efficiency. Hoisted battery swapping, although enabling rapid battery module replacement, faces severe space constraints when used inside tunnels. The clearance height inside tunnels is typically limited, failing to provide sufficient operating space for hoisting equipment. This is especially true in construction environments with strictly limited clearance, such as shield tunnels and mine roadways, where traditional hoisted battery swapping equipment simply cannot enter or operate normally. Furthermore, tunnels typically contain ventilation ducts, lighting facilities, monitoring equipment, and other ancillary facilities, further reducing available vertical space, making hoisted battery swapping, which relies on vertical lifting, unsuitable for the battery swapping needs within tunnels. Existing manual handling and replacement methods, while not subject to clearance restrictions, suffer from high labor intensity, high safety risks, and low operational efficiency, and lack automation, failing to meet the efficiency requirements of modern tunnel construction.

[0025] To address this technical problem, this invention proposes a mobile battery swapping device for tunnel construction machinery.

[0026] Please see Figure 1In one embodiment of the present invention, the tunnel construction machinery is a new energy construction equipment 10, which extends along the X direction. The mobile battery swapping device for the tunnel construction machinery includes a moving mechanism 100, a modular energy storage structure 200, and a battery swapping mechanism 300. The moving mechanism 100 extends along the Y direction and is located on one side of the new energy construction equipment 10. The modular energy storage structure 200 is detachably connected to the power supply terminal of the new energy construction equipment 10. The battery swapping mechanism 300 is located on the moving mechanism 100 and extends along the Y direction. The battery swapping mechanism 300 can be raised to the receiving position 301 or lowered to the discharge position 302. The battery swapping mechanism 300 can also extend along the Y direction to the extended position 303 or retract to the initial position. Position 304; wherein, when the battery swapping mechanism 300 is set in the receiving position 301 and is in the initial position 304, the battery swapping mechanism 300 is used to extend to the extended position and connect with the modular energy storage structure 200 and then retract, so as to drive the modular energy storage structure 200 to slide along the Y direction to the initial position 304 and charge, and then drive the modular energy storage structure 200 to descend to the discharge position 302; or, when the battery swapping mechanism 300 is set in the discharge position 302 and is in the initial position 304, the battery swapping mechanism 300 is used to connect with the modular energy storage structure 200, extend to the extended position 303 and reset to the initial position 304, so as to drive the modular energy storage structure 200 to slide along the Y direction to the extended position 303 and electrically connect with the power supply end of the new energy construction equipment 10.

[0027] It should be noted that the new energy construction equipment 10 in this application may be, but is not limited to, articulated dump trucks, skid steer loaders, excavators and articulated loaders, and the tunnel construction machinery used in this application is the new energy construction equipment 10 located in the tunnel under construction, which is construction equipment that needs to perform battery swapping operations in the tunnel under construction.

[0028] Specifically, the tunnel construction machinery is a new energy construction equipment 10, which is battery-powered, avoiding the exhaust emissions problems of traditional fuel-powered equipment in the tunnel. The new energy construction equipment 10 extends along the X direction, and the moving mechanism 100 extends along the Y direction, where the Y direction is perpendicular to the X direction. The moving mechanism 100 is located on one side of the new energy construction equipment 10 and contacts the tunnel ground through wheels or tracks, enabling it to move and position itself along the Y direction to the side of the new energy construction equipment 10.

[0029] The modular energy storage structure 200 is detachably connected to the power supply terminal of the new energy construction equipment 10. The modular energy storage structure 200 integrates a lithium battery pack and is electrically connected to the power supply terminal of the new energy construction equipment 10 via a pluggable electrical connector. When replacement is needed, quick separation and connection can be achieved through a plug-and-play operation. The battery swapping mechanism 300 is located within the moving mechanism 100. As the core actuator of the moving mechanism 100, the battery swapping mechanism 300 performs the functions of grasping, transporting, and positioning the modular energy storage structure 200. The battery swapping mechanism 300 extends along the Y-direction, and its main motion trajectory is consistent with the extension direction of the moving mechanism 100, achieving linear movement along the Y-direction.

[0030] More specifically, the battery swapping mechanism 300 can rise to the receiving position 301 or descend to the discharging position 302. The receiving position 301 is located above or to the side of the new energy construction equipment 10, used to receive the modular energy storage structure 200 to be charged; the discharging position 302 is located below or to the side of the new energy construction equipment 10, used to transport the fully charged modular energy storage structure 200 to the new energy construction equipment 10. The battery swapping mechanism 300 can also extend along the Y direction to the extended position 303 or retract to the initial position 304. The initial position 304 is the standby position of the battery swapping mechanism 300, and the extended position 303 is the working position where the battery swapping mechanism 300 can reach the modular energy storage structure 200 after being fully extended.

[0031] The mobile battery swapping device for tunnel construction machinery described in this application, through the aforementioned structural configuration, effectively solves the battery swapping problem in tunnels with limited clearance. When the battery swapping mechanism 300 is positioned at the receiving position 301 and in the initial position 304, the battery swapping mechanism 300 extends to the extended position and connects with the modular energy storage structure 200 before retracting. This causes the modular energy storage structure 200 to slide along the Y direction to the initial position 304 and be charged, and then descends to the discharge position 302. In specific implementation, the battery swapping mechanism 300 first rises to the receiving position 301, where it is in the initial retracted state. Subsequently, the battery swapping mechanism 300 extends along the Y direction to the extended position 303, establishing a mechanical connection with the modular energy storage structure 200 to be replaced. A reliable connection is achieved through clamping or snap-fitting. After the connection is completed, the battery swapping mechanism 300 retracts to the initial position 304. During this process, the modular energy storage structure 200 slides along the Y direction, pulling it from the new energy construction equipment 10 to the charging position of the mobile mechanism 100. After the modular energy storage structure 200 reaches the initial position 304, it automatically docks with the charging device on the moving mechanism 100 and begins the charging process. After charging is completed, the battery swapping mechanism 300 lowers the fully charged modular energy storage structure 200 to the discharge position 302, preparing for subsequent installation operations.

[0032] When the battery swapping mechanism 300 is positioned at the discharge position 302 and in the initial position 304, it extends to the extended position 303 after connecting with the modular energy storage structure 200 and then returns to the initial position 304. This allows the modular energy storage structure 200 to slide along the Y direction to the extended position 303 and connect electrically with the power supply end of the new energy construction equipment 10. During installation, the battery swapping mechanism 300 first descends to the discharge position 302 and establishes a connection with the already charged modular energy storage structure 200. Then, the battery swapping mechanism 300 extends along the Y direction to the extended position 303, pushing the modular energy storage structure 200 to slide along the Y direction until the plug 230 of the modular energy storage structure 200 is fully connected to the socket 13 of the power supply end of the new energy construction equipment 10. After connection, the battery swapping mechanism 300 returns to the initial position 304, releasing the connection to the modular energy storage structure 200 and completing the entire battery swapping process.

[0033] This application presents a mobile battery swapping device for tunnel construction machinery, employing a horizontal push-pull battery swapping method that completely avoids the reliance on vertical space inherent in traditional hoisting battery swapping. The mobile mechanism 100 can move flexibly along the side of the tunnel, while the battery swapping mechanism 300, through a combination of telescopic and lifting movements along the Y-direction, automatically grasps, charges, and installs the modular energy storage structure 200. Compared to traditional hoisting battery swapping methods, this battery swapping device can operate normally under the limited clearance conditions within the tunnel, effectively solving the problem of vertical space occupation by ventilation ducts, lighting facilities, and other ancillary facilities. Simultaneously, the entire battery swapping process is automated, significantly reducing manual labor intensity and safety risks, and improving battery swapping efficiency. Through a detachable electrical connection between the modular energy storage structure 200 and the power supply end of the new energy construction equipment 10, rapid battery replacement is achieved, avoiding the impact of prolonged charging on construction progress and ensuring that the new energy construction equipment 10 can continuously and efficiently perform construction operations within the tunnel.

[0034] Please continue reading. Figure 1 In an embodiment of the present invention, the moving mechanism 100 includes an integral frame 110 and a loading plate 120, both of which extend along the Y direction, and the battery swapping mechanism 300 is mounted on the loading plate 120.

[0035] Specifically, the integral frame 110 bears the weight of the entire mobile battery swapping device, and its bottom is equipped with a set of wheels or a track system, enabling the mobile mechanism 100 to move along the tunnel floor. The integral frame 110 and the loading plate 120 are rigidly connected to form an integrated structure. The loading plate 120 is located above the integral frame 110, providing a working platform for the battery swapping mechanism 300. The surface flatness and levelness of the loading plate 120 directly affect the working accuracy of the battery swapping mechanism 300; therefore, the loading plate 120 is machined to ensure its surface quality.

[0036] More specifically, the structural configuration of both the integrated frame 110 and the loading plate 120 extending along the Y direction enables the moving mechanism 100 to be precisely positioned and moved laterally within the tunnel. When the moving mechanism 100 needs to approach the new energy construction equipment 10 for battery swapping operations, the integrated frame 110 drives the entire device to move along the Y direction to a suitable position, and the battery swapping mechanism 300 on the loading plate 120 can accurately align with the modular energy storage structure 200 on the new energy construction equipment 10. The structural arrangement of the battery swapping mechanism 300 mounted on the loading plate 120 ensures that the working height and working range of the battery swapping mechanism 300 can cover the power supply area of ​​the new energy construction equipment 10.

[0037] This embodiment effectively improves the overall rigidity and stability of the mobile battery swapping device through the integrated structure of the integral frame 110 and the loading plate 120. The integral frame 110 bears the main load-bearing function and can withstand various loads generated during the battery swapping process, including the weight of the modular energy storage structure 200, the reaction force of the battery swapping mechanism 300, and the inertial force during movement. The loading plate 120 serves as a dedicated mounting platform for the battery swapping mechanism 300, and its extension along the Y direction is consistent with the working direction of the battery swapping mechanism 300, ensuring that the battery swapping mechanism 300 can extend, retract, and lift along a predetermined trajectory. Compared with a split structure, the integral frame 110 reduces the number of connection points, lowers structural complexity and failure risk, and improves the reliability and durability of the entire mobile battery swapping device in the harsh environment of tunnels.

[0038] Please continue reading. Figure 1 And see Figure 2 In an embodiment of the present invention, the new energy construction equipment 10 includes an upper frame 11, a support platform 12, and a socket 13. The upper frame 11 extends along the X direction, and the support platform 12 extends along the Y direction. The support platform 12 is installed on the upper frame 11. The battery swapping mechanism 300 is located on one side of the upper frame 11 corresponding to the position of the support platform 12. The socket 13 is installed on the end of the support platform 12 away from the upper frame 11. The socket 13 forms the power supply end of the new energy construction equipment 10. The modular energy storage structure 200 is detachably plugged into the socket 13 along the Y direction and electrically connected to the socket 13.

[0039] Specifically, the upper frame 11 serves as the main load-bearing structure of the new energy construction equipment 10, and its extension along the X-direction allows the entire construction equipment to adapt to the spatial constraints within the tunnel. The load-bearing platform 12 extends perpendicularly to the upper frame 11 along the Y-direction, forming a reasonable spatial layout between the upper frame 11 and the moving mechanism 100. One end of the load-bearing platform 12 is connected to the upper frame 11, and the other end extends to a position close to the moving mechanism 100, providing an installation foundation for the modular energy storage structure 200.

[0040] More specifically, during the installation of the support platform 12 on the upper frame 11, the support platform 12 is rigidly connected to the upper frame 11 through multiple connection points, ensuring that the support platform 12 will not deform or loosen when bearing the weight of the modular energy storage structure 200. The surface of the support platform 12 is provided with guide grooves or positioning holes to guide the accurate installation of the modular energy storage structure 200. The arrangement of the battery swapping mechanism 300 on one side of the upper frame 11, corresponding to the position of the support platform 12, ensures that the battery swapping mechanism 300 can accurately contact the modular energy storage structure 200 on the support platform 12. The extension and lifting strokes of the battery swapping mechanism 300 can cover the working area of ​​the modular energy storage structure 200 on the support platform 12.

[0041] The socket 13 is installed at the end of the support platform 12 away from the upper frame 11, i.e., at the free end of the support platform 12. This arrangement places the socket 13 closest to the moving mechanism 100, facilitating operation by the battery swapping mechanism 300. The socket 13 integrates electrical contacts and a mechanical locking device. When the modular energy storage structure 200 is inserted into the socket 13 along the Y direction, the electrical contacts first establish an electrical connection, and then the mechanical locking device activates, firmly locking the modular energy storage structure 200 within the socket 13. The socket 13 forms the technical feature of the power supply end of the new energy construction equipment 10, making it the power input interface for the entire new energy construction equipment 10. The modular energy storage structure 200 provides power to various electrical systems of the new energy construction equipment 10 through the socket 13.

[0042] In the implementation of the modular energy storage structure 200 being detachably plugged into the socket 13 along the Y direction, the plug 230 of the modular energy storage structure 200 is inserted into the socket 13 along the Y direction, and the plug 230 and the socket 13 achieve precise connection through a male-female mating method. During the insertion process, the guide portion of the modular energy storage structure 200 first contacts the guide portion of the socket 13 to ensure the correct insertion direction. Subsequently, the electrical contacts gradually establish a connection, and finally, the mechanical locking device fixes the modular energy storage structure 200 in the socket 13. During disassembly, by releasing the mechanical locking device, the modular energy storage structure 200 can be pulled out of the socket 13 along the Y direction, enabling quick replacement.

[0043] This embodiment achieves a structural layout suitable for battery swapping operations within tunnels through the coordinated configuration of the upper frame 11, the support platform 12, and the socket 13. The upper frame 11 extends along the X-direction, aligning with the tunnel axis; the support platform 12 extends along the Y-direction, aligning with the working direction of the battery swapping mechanism 300; and the socket 13 is positioned at the free end of the support platform 12, placing it in the optimal working position for the battery swapping mechanism 300. Compared to traditional top-mounted installations, the lateral extension of the support platform 12 effectively utilizes the tunnel's lateral space, avoiding encroachment on the tunnel's clearance height. The insertion and removal operation of the modular energy storage structure 200 along the Y-direction aligns with the pushing and pulling action of the battery swapping mechanism 300, achieving a high degree of coordination in the battery swapping process and ensuring the accuracy and reliability of the battery swapping operation.

[0044] Please continue reading. Figure 1 and Figure 2 And see Figure 3 In an embodiment of the present invention, the new energy construction equipment 10 further includes a locking mechanism 14. An installation space 101 is provided between the upper frame 11 and the bearing platform 12. The locking mechanism 14 is housed in the installation space 101. The connecting end of the locking mechanism 14 is installed on the upper frame 11. The free end of the locking mechanism 14 can be raised to the locking position 102 to abut against one side of the modular energy storage structure 200 on the new energy construction equipment 10, or can be lowered to the reset position 103 to disengage from one side of the modular energy storage structure 200 on the new energy construction equipment 10.

[0045] Specifically, the installation space 101 between the upper frame 11 and the support platform 12 is formed at their connection point. As the support platform 12 extends outward from the upper frame 11, a triangular or rectangular installation space 101 is naturally formed at the connection point. The height of this space is determined by the structural height of the upper frame 11, and the width is determined by the installation width of the support platform 12. The arrangement of the locking mechanism 14 within the installation space 101 fully utilizes the unused space inside the new energy construction equipment 10 and avoids the locking mechanism 14 occupying the external working area.

[0046] More specifically, in the implementation of the locking mechanism 14, the connecting end is installed on the upper frame 11. The connecting end is connected to the inner wall of the upper frame 11 through a flange or bracket 310, forming a solid installation base. The locking mechanism 14 adopts a hinged or sliding connection, allowing its free end to move vertically. When the locking mechanism 14 is in the reset position 103, the free end is located at the bottom of the installation space 101, flush with or slightly lower than the surface of the support platform 12, and will not interfere with the insertion and removal operation of the modular energy storage structure 200.

[0047] During the process of the locking mechanism 14 rising to the locking position 102, the free end moves upward from inside the installation space 101, passes through the preset opening on the support platform 12, and finally abuts against the side of the modular energy storage structure 200 already installed on the support platform 12. In the locking position 102, the free end applies a lateral clamping force to the modular energy storage structure 200, forming a double safety net with the insertion and removal fixing of the socket 13, ensuring that the modular energy storage structure 200 will not loosen due to vibration or impact during the operation of the new energy construction equipment 10. The surface of the free end of the locking mechanism 14 is provided with a rubber pad or buffer pad to avoid damage to the outer shell of the modular energy storage structure 200.

[0048] When the modular energy storage structure 200 needs to be replaced, the free end of the locking mechanism 14 descends to the reset position 103, disengaging from the side of the modular energy storage structure 200, providing sufficient space for the operation of the battery swapping mechanism 300. In the reset position 103, the free end is completely retracted into the installation space 101, without interfering with the pushing and pulling motion of the battery swapping mechanism 300 along the Y direction. Combined with the technical feature in the independent claim that the battery swapping mechanism 300 can extend to the extended position 303 to drive the modular energy storage structure 200 to slide, the lifting and lowering motion of the locking mechanism 14 and the extension and retraction motion of the battery swapping mechanism 300 are coordinated. Before the battery swapping process begins, the locking mechanism 14 resets first, and after the battery swapping is completed, the locking mechanism 14 rises again to lock.

[0049] This embodiment further enhances the installation reliability of the modular energy storage structure 200 on the new energy construction equipment 10 by adding a locking mechanism 14. The locking mechanism 14 is compactly arranged within the installation space 101, effectively utilizing the unused space between the upper frame 11 and the support platform 12 without increasing the overall dimensions of the new energy construction equipment 10. The lifting action of the locking mechanism 14 complements the plugging and unplugging fixing of the socket 13. The socket 13 mainly undertakes the functions of electrical connection and axial fixation, while the locking mechanism 14 mainly undertakes the functions of lateral fixation and anti-loosening. Compared with the solution that relies solely on the socket 13 for fixation, the dual fixing method after adding the locking mechanism 14 can effectively cope with various vibration and impact loads during tunnel construction, ensuring the installation stability of the modular energy storage structure 200 under harsh working conditions and avoiding electrical connection interruptions or safety accidents caused by loosening.

[0050] Please continue reading. Figure 3In an embodiment of the present invention, the locking mechanism 14 includes a first lifting drive member 141, a locking piece 142, and a connecting plate 143. The connecting end of the first lifting drive member 141 is mounted on the upper frame 11, and the free end of the first lifting drive member 141 is connected to the connecting plate 143. The connecting plate 143 extends along the X direction, and the locking piece 142 extends vertically. The bottom end of the locking piece 142 is connected to the connecting plate 143. The free end of the first lifting drive member 141 is used to drive the connecting plate 143 to rise so that the connecting plate 143 is pressed upward against the bearing plate. The bottom of the platform 12 is used to drive the locking plate 142 to extend upward above the bearing platform 12, so that the locking plate 142 is in the locked position 102 to press against one side of the modular energy storage structure 200 on the new energy construction equipment 10, or to drive the connecting plate 143 to descend so that the connecting plate 143 moves downward away from the bottom of the bearing platform 12, so that the locking plate 142 retracts downward below the bearing platform 12, so that the locking plate 142 is in the reset position 103 to disengage from one side of the modular energy storage structure 200 on the new energy construction equipment 10.

[0051] Specifically, the first lifting drive component 141 is installed inside the mounting space 101 between the upper frame 11 and the support platform 12. The first lifting drive component 141 is in the form of a cylinder, hydraulic cylinder, or electric push rod, with its connecting end fixed to the inner wall of the upper frame 11, and its free end capable of vertical lifting movement. After the connecting plate 143 is connected to the free end of the first lifting drive component 141, it can move up and down synchronously with the movement of the first lifting drive component 141.

[0052] More specifically, the structural configuration of the connecting plate 143 extending along the X-direction allows it to span the width of the support platform 12, providing a support platform for the installation of multiple locking plates 142. The length of the connecting plate 143 is determined according to the width of the support platform 12, ensuring that the locking plates 142 can cover the effective contact area of ​​the modular energy storage structure 200. The arrangement of the locking plates 142 extending vertically and connected to the connecting plate 143 at their bottom ends allows the locking plates 142 to move vertically up and down under the drive of the connecting plate 143. There can be one or more locking plates 142, which are distributed and arranged along the extension direction of the connecting plate 143.

[0053] The free end of the first lifting drive component 141 is used to drive the connecting plate 143 to rise, thereby causing the connecting plate 143 to press against the bottom of the support platform 12, and causing the locking piece 142 to extend upward above the support platform 12, so that the locking piece 142 is in the locked position 102, pressing against one side of the modular energy storage structure 200 on the new energy construction equipment 10. In the specific implementation of the locking process, the free end of the first lifting drive component 141 moves upward, driving the connecting plate 143 to rise synchronously. During the rising process, the connecting plate 143 gradually approaches the bottom of the support platform 12. When the connecting plate 143 rises to contact the bottom of the support platform 12, the upper surface of the connecting plate 143 forms a surface contact with the lower surface of the support platform 12. At this time, the top part of the locking piece 142 passes through the preset through hole on the support platform 12 and extends above the support platform 12. After the locking piece 142 extends above the support platform 12, its side contacts the side wall of the modular energy storage structure 200 installed on the support platform 12, applying a lateral clamping force to the modular energy storage structure 200 to achieve the locking function.

[0054] The free end of the first lifting drive component 141 is used to drive the connecting plate 143 downward, causing the connecting plate 143 to move downward away from the bottom of the support platform 12, thereby causing the locking plate 142 to retract downward below the support platform 12, so that the locking plate 142 is in the reset position 103 and disengaged from one side of the modular energy storage structure 200 on the new energy construction equipment 10. In the specific implementation of the reset process, the free end of the first lifting drive component 141 moves downward, driving the connecting plate 143 to descend synchronously, and the connecting plate 143 gradually moves away from the bottom of the support platform 12. As the connecting plate 143 descends, the locking plate 142 also moves downward synchronously, and the top of the locking plate 142 gradually exits the through hole on the support platform 12, completely retracting below the support platform 12. At this time, the locking plate 142 is completely disengaged from the modular energy storage structure 200, providing sufficient space for the operation of the battery swapping mechanism 300.

[0055] This embodiment achieves precise control and reliable locking of the locking mechanism 14 through the coordinated operation of the first lifting drive component 141, the connecting plate 143, and the locking plates 142. The first lifting drive component 141 provides a stable driving force, and the connecting plate 143, as a force transmission platform, evenly distributes the driving force to each locking plate 142. The locking plates 142 directly contact the modular energy storage structure 200 to achieve the locking function. The arrangement of the connecting plate 143 extending along the X direction is consistent with the structural direction of the upper frame 11, making full use of the geometric features of the installation space 101. The vertically extending arrangement of the locking plates 142 allows them to effectively penetrate the bearing platform 12 to achieve the locking action. Compared with the single-point locking method, the structure of the connecting plate 143 supporting multiple locking plates 142 can achieve multi-point synchronous locking, improving the uniformity and reliability of locking. Combined with the pushing and pulling action of the battery swapping mechanism 300 in the aforementioned claims, the lifting action of the locking mechanism 14 and the working rhythm of the battery swapping mechanism 300 form an orderly coordination, ensuring the safety and efficiency of the battery swapping process.

[0056] Please continue reading. Figure 1 And see Figure 4 and Figure 5In an embodiment of the present invention, the battery swapping mechanism 300 includes a bracket 310, a support plate 320, a column 330, a multi-section telescopic rod 340, a second lifting drive component 350, a charging base 360, and a connecting structure 370. The bracket 310 extends along the Y direction and includes a receiving section 311A ​​and a discharging section 312A, with the receiving section 311A ​​spaced above the discharging section 312A. The extension direction of the support plate 320 is consistent with the extension direction of the bracket 310, and the support plate 320 is spaced on one side of the bracket 310. The column 330 extends vertically, and both the column 330 and the charging base 360 ​​are connected to the end of the support plate 320 away from the bracket 310. The connecting end of the telescopic rod 340 is connected to the top of the column 330. The free end of the multi-section telescopic rod 340 is connected to the connecting structure 370. The free end of the multi-section telescopic rod 340 can extend along the Y direction to the extended position 303 or retract to the initial position 304. The connecting structure 370 can descend to the abutment position 305 or rise to the release position 306. The free end of the second lifting drive 350 is connected to the bearing plate 320. The second lifting drive 350 is used to drive the bearing plate 320, column 330, multi-section telescopic rod 340 and connecting structure 370 to rise to the receiving position 301 or descend to the discharge position 302. When the bearing plate 320 is set in the receiving position 301 and the multi-section telescopic rod 340 is in the receiving position 302, the multi-section telescopic rod 340 can extend along the Y direction to the extended position 303 or retract to the initial position 304. When the free end of the telescopic rod 340 is in the initial position 304, the free end of the multi-section telescopic rod 340 is used to extend to the extended position so that the connecting structure 370 moves to the side of the modular energy storage structure 200 away from the bracket 310. The connecting structure 370 descends to the abutment position 305 and abuts against the modular energy storage structure 200. The free end of the multi-section telescopic rod 340 retracts to the initial position 304 so that the modular energy storage structure 200 is pulled along the bracket 310 through the receiving section 311A ​​to the initial position 304 and detachably connected to the charging base 360 ​​to charge the modular energy storage structure 200. Then, the second lifting drive component 350 drives the modular energy storage structure 200 to charge. The energy storage structure 200 descends to the discharge position 302, and the connecting structure 370 rises to the release position 306; or, when the bearing plate 320 is set at the discharge position 302 and the free end of the multi-section telescopic rod 340 is in the initial position 304, the connecting structure 370 descends to the abutment position 305 and abuts against the side of the modular energy storage structure 200 away from the support 310. The free end of the multi-section telescopic rod 340 is used to extend to the extension position 303 and reset to the initial position 304, so that the modular energy storage structure 200 can be pushed along the support 310 through the discharge section 312A to the extension position 303 and electrically connected to the power supply end of the new energy construction equipment 10.

[0057] Specifically, the battery swapping mechanism 300 includes a bracket 310, a support plate 320, a column 330, a multi-section telescopic rod 340, a second lifting drive component 350, a charging base 360, and a connecting structure 370. The bracket 310 serves as the main load-bearing frame of the battery swapping mechanism 300, the support plate 320 serves as the mounting platform for each component, the column 330 serves as the vertical support structure, the multi-section telescopic rod 340 serves as the horizontal pushing and pulling power device, the second lifting drive component 350 serves as the vertical lifting power device, the charging base 360 ​​serves as the charging interface for the modular energy storage structure 200, and the connecting structure 370 serves as the connection interface with the modular energy storage structure 200. The bracket 310 extends along the Y direction, which is a transverse direction perpendicular to the tunnel axis, and the extension direction of the bracket 310 is consistent with the movement direction of the moving mechanism 100. The support 310 includes a receiving section 311A ​​and a discharging section 312A. The receiving section 311A ​​is spaced above the discharging section 312A. The receiving section 311A ​​is located on the upper layer of the support 310, and the discharging section 312A is located on the lower layer of the support 310. A certain vertical distance is maintained between the two sections.

[0058] More specifically, the support frame 310, as the main structure of the battery swapping mechanism 300, extends along the Y direction, enabling the entire battery swapping mechanism 300 to approach or move away from the new energy construction equipment 10 along the Y direction under the drive of the moving mechanism 100. The receiving section 311A ​​and the discharge section 312A of the support frame 310 are arranged in layers, forming a bidirectional transmission channel for the modular energy storage structure 200. The receiving section 311A ​​is used to receive the modular energy storage structure 200 to be charged, and the discharge section 312A is used to transport the modular energy storage structure 200 that has been charged.

[0059] The extension direction of the support plate 320 is consistent with the extension direction of the bracket 310. The support plates 320 are spaced apart on one side of the bracket 310, extending along the Y direction and arranged parallel to the bracket 310, maintaining a certain lateral distance between them. The column 330 extends vertically, and both the column 330 and the charging base 360 ​​are connected to the end of the support plate 320 away from the bracket 310. The column 330 is vertically installed at the free end of the support plate 320, and the charging base 360 ​​is also installed at the same end of the support plate 320. The column 330 provides a vertical mounting base for the multi-section telescopic pole 340, and the charging base 360 ​​provides charging functionality for the modular energy storage structure 200.

[0060] The connecting end of the multi-section telescopic rod 340 is connected to the top of the column 330, and the free end of the multi-section telescopic rod 340 is connected to the connecting structure 370. The multi-section telescopic rod 340 forms a hinged connection with the top of the column 330 through its connecting end, and the free end is connected to the connecting structure 370 through a connector. The free end of the multi-section telescopic rod 340 can extend along the Y direction to the extended position 303 or retract to the initial position 304. The telescopic rod 340 achieves the telescopic movement of its free end through an internal telescopic drive device. The connecting structure 370 can descend to the abutment position 305 or rise to the release position 306. The connecting structure 370 achieves vertical lifting movement through a lifting drive device.

[0061] The free end of the second lifting drive component 350 is connected to the support plate 320. The second lifting drive component 350 forms a connection with the support plate 320 through its free end, driving the support plate 320 and the components installed on it to perform vertical lifting and lowering movements. The second lifting drive component 350 is used to drive the support plate 320, the column 330, the multi-section telescopic rod 340 and the connecting structure 370 to rise to the receiving position 301 or to fall to the discharge position 302. The second lifting drive component 350 can drive the entire support plate 320 assembly to move up and down between the receiving position 301 and the discharge position 302. The receiving position 301 corresponds to the height of the receiving section 311A ​​of the bracket 310, and the discharge position 302 corresponds to the height of the discharge section 312A of the bracket 310.

[0062] When the support plate 320 is positioned at the receiving position 301 and the free end of the multi-section telescopic rod 340 is in the initial position 304, the support plate 320 is at the corresponding height of the receiving section 311A ​​of the bracket 310, and the multi-section telescopic rod 340 is in a retracted state. At this time, the battery swapping mechanism 300 executes the receiving and charging process of the modular energy storage structure 200: the free end of the multi-section telescopic rod 340 is used to extend to the extended position so that the connecting structure 370 moves to the side of the modular energy storage structure 200 away from the bracket 310. After the multi-section telescopic rod 340 extends, the connecting structure 370 moves to the far end position of the modular energy storage structure 200. The connecting structure 370 descends to the abutment position 305 and abuts against the modular energy storage structure 200, and the connecting structure 370 descends and contacts the end face of the modular energy storage structure 200. The free end of the multi-section telescopic rod 340 retracts to the initial position 304, so that the modular energy storage structure 200 can be detachably inserted into the charging base 360 ​​by the connecting structure 370, sliding along the support 310 through the receiving section 311A. When the multi-section telescopic rod 340 retracts, the connecting structure 370 pulls the modular energy storage structure 200 to slide along the receiving section 311A ​​of the support 310, and finally docks with the charging base 360. The modular energy storage structure 200 is charged, and then the second lifting drive 350 drives the modular energy storage structure 200 to descend to the discharge position 302, while the connecting structure 370 rises to the release position 306. After charging is completed, the second lifting drive 350 drives the support plate 320 to descend to the discharge position 302, and the connecting structure 370 rises and disengages from the modular energy storage structure 200.

[0063] When the support plate 320 is positioned at the discharge position 302 and the free end of the multi-section telescopic rod 340 is in the initial position 304, the support plate 320 is at the corresponding height of the discharge section 312A of the bracket 310, and the multi-section telescopic rod 340 is in a retracted state. At this time, the battery swapping mechanism 300 executes the discharge and installation process of the modular energy storage structure 200: the connecting structure 370 descends to the abutment position 305 and abuts against the side of the modular energy storage structure 200 away from the bracket 310, and the connecting structure 370 descends and contacts the charged modular energy storage structure 200. The free end of the multi-section telescopic rod 340 is used to extend to the extended position 303 and return to the initial position 304, so as to push the modular energy storage structure 200 along the support 310 through the discharge section 312A to the extended position 303 and electrically connect it to the power supply end of the new energy construction equipment 10. When the multi-section telescopic rod 340 extends, the connecting structure 370 pushes the modular energy storage structure 200 along the discharge section 312A of the support 310, and finally pushes it to the power supply end position of the new energy construction equipment 10 and establishes an electrical connection.

[0064] This embodiment achieves an automated battery swapping process for the modular energy storage structure 200 through the segmented structure of the support 310 and the lifting coordination of the support plate 320. The receiving section 311A ​​and the discharge section 312A of the support 310 are arranged in layers, providing a clear transmission path for the modular energy storage structure 200 and avoiding interference between the modular energy storage structures 200 to be charged and those already charged. The coordinated movement of the multi-section telescopic rod 340 and the connecting structure 370 precisely controls the pushing and pulling motion of the modular energy storage structure 200, ensuring the positional accuracy of the modular energy storage structure 200 during transmission. The lifting function of the second lifting drive component 350 works in conjunction with the segmented structure of the support 310, enabling the same battery swapping mechanism 300 to complete the entire process of receiving, charging, and discharging at different height levels. Compared to single-layer battery swapping, the dual-layer segmented structure improves battery swapping efficiency and reduces waiting time during the swapping process. At the same time, the integration of the charging base 360 ​​enables integrated operation of battery swapping and charging, ensuring the continuous charging capability of the modular energy storage structure 200 during the battery swapping process.

[0065] Please continue reading. Figure 5 In an embodiment of the present invention, the connecting structure 370 includes a mounting plate 371, a third lifting drive member 372, and a connecting piece 373. The mounting plate 371 is mounted on the free end of the multi-section telescopic rod 340. The connecting piece 373 extends vertically. The connecting end of the third lifting drive member 372 is mounted on the mounting plate 371. The free end of the third lifting drive member 372 is connected to the connecting piece 373. The third lifting drive member 372 is used to drive the connecting piece 373 to descend to the abutment position 305 or rise to the release position 306.

[0066] Specifically, the connecting structure 370 includes a mounting plate 371, a third lifting drive component 372, and a connecting piece 373. The mounting plate 371 serves as the mounting base for the connecting structure 370, the third lifting drive component 372 serves as the lifting power source for the connecting piece 373, and the connecting piece 373 serves as a connecting component that directly contacts the modular energy storage structure 200. The mounting plate 371 is installed on the free end of the multi-section telescopic rod 340 and is fixed to the free end face of the multi-section telescopic rod 340 by bolts or welding, forming a stable mounting base. The connecting piece 373 extends vertically, and its extension direction is perpendicular to the mounting surface of the mounting plate 371. The connecting end of the third lifting drive component 372 is installed on the mounting plate 371, and the third lifting drive component 372 forms a fixed connection with the mounting plate 371 through its connecting end. The connecting end is connected to the mounting plate 371 by a flange connection. The free end of the third lifting drive component 372 is connected to the connecting piece 373, and the free end is connected to the upper end of the connecting piece 373 through a connector to form a force transmission connection. The third lifting drive component 372 is used to drive the connecting piece 373 to descend to the abutment position 305 or rise to the release position 306.

[0067] More specifically, the mounting plate 371 serves as the connection interface between the connecting structure 370 and the multi-section telescopic rod 340, undertaking the dual functions of transmitting the pushing and pulling force of the multi-section telescopic rod 340 and supporting the various components of the connecting structure 370. The arrangement of the mounting plate 371 at the free end of the multi-section telescopic rod 340 allows the connecting structure 370 to move synchronously with the telescopic movement of the multi-section telescopic rod 340, achieving precise positioning of the connecting structure 370 in the Y direction.

[0068] During the connection between the mounting plate 371 and the free end of the multi-section telescopic rod 340, the mounting surface of the mounting plate 371 forms surface contact with the end face of the multi-section telescopic rod 340, and is reliably fixed by multiple bolts. The thickness and strength of the mounting plate 371 are matched according to the weight of the third lifting drive component 372 and the connecting piece 373 as well as the working load, ensuring that the mounting plate 371 will not deform or be damaged when subjected to various working loads. The vertically extending arrangement of the connecting piece 373 is consistent with the side wall direction of the modular energy storage structure 200, which facilitates effective contact and fit between the connecting piece 373 and the modular energy storage structure 200.

[0069] In the specific implementation process where the connecting end of the third lifting drive component 372 is installed on the mounting plate 371, the third lifting drive component 372 adopts the form of a small cylinder, electric push rod, or hydraulic cylinder. Its connecting end mates with the preset mounting holes of the mounting plate 371 through a flange, and is rigidly connected by bolts. The axial direction of the third lifting drive component 372 is consistent with the extension direction of the connecting piece 373, ensuring that the driving force can be effectively transmitted to the connecting piece 373. When the free end of the third lifting drive component 372 is connected to the connecting piece 373, the connecting joint of the free end and the connecting hole of the connecting piece 373 form a pin connection or threaded connection, allowing the connecting piece 373 to perform vertical lifting movement under the drive of the third lifting drive component 372.

[0070] During the process of driving the connecting piece 373 to descend to the abutment position 305, the free end of the third lifting drive component 372 extends downward, driving the connecting piece 373 to descend synchronously. During the descent of the connecting piece 373, its bottom end gradually approaches the side wall or end face of the modular energy storage structure 200. When the connecting piece 373 descends to the preset position, the contact surface of the connecting piece 373 forms reliable contact with the modular energy storage structure 200, at which point the connecting piece 373 is in the abutment position 305. In the abutment position 305, the connecting piece 373 applies appropriate contact pressure to the modular energy storage structure 200, ensuring that the pushing and pulling force can be effectively transmitted to the modular energy storage structure 200 when the multi-section telescopic rod 340 performs pushing and pulling actions.

[0071] During the process of the third lifting drive component 372 driving the connecting piece 373 to rise to the release position 306, the free end of the third lifting drive component 372 retracts upward, driving the connecting piece 373 to rise synchronously. During the rise of the connecting piece 373, its bottom end gradually disengages from the modular energy storage structure 200. When the connecting piece 373 rises to a preset height, it completely separates from the modular energy storage structure 200, at which point the connecting piece 373 is in the release position 306. In the release position 306, the connecting piece 373 does not exert any constraint on the modular energy storage structure 200, providing space for the free movement or other operations of the modular energy storage structure 200.

[0072] This embodiment achieves precise control and reliable connection of the connection structure 370 through the coordinated operation of the mounting plate 371, the third lifting drive component 372, and the connecting piece 373. The mounting plate 371 provides a stable mounting base for the third lifting drive component 372, the third lifting drive component 372 provides precise lifting control for the connecting piece 373, and the connecting piece 373 directly contacts the modular energy storage structure 200 to achieve the connection function. Combined with the workflow of the battery swapping mechanism 300 pushing or pulling the modular energy storage structure 200 through the connection structure 370 in the aforementioned claims, the lifting action of the connecting piece 373 and the telescopic action of the multi-section telescopic rod 340 are timed together. When connection is needed, the connecting piece 373 descends to the abutment position 305 to establish a connection; when release is needed, the connecting piece 373 rises to the release position 306 to disengage. Compared to fixed connection methods, the controllable lifting function of the connecting piece 373 improves the flexibility and reliability of the connection, avoids interference to the modular energy storage structure 200 when the connection is not needed, and ensures effective connection when push and pull forces need to be transmitted, thus realizing precise control and safe operation of the battery swapping process.

Figure 5 In an embodiment of the present invention, the charging base 360 ​​has a charging port 361 on the side facing the bracket 310, and the modular energy storage structure 200 is detachably plugged into the charging port 361 along the Y direction, and the charging port 361 is electrically connected to the modular energy storage structure 200.

[0074] Specifically, a charging port 361 is provided on the side of the charging base 360 ​​facing the bracket 310. The charging port 361 is located on the side wall of the charging base 360 ​​facing the bracket 310, and the opening direction of the charging port 361 is consistent with the extension direction of the bracket 310. The modular energy storage structure 200 is detachably inserted into the charging port 361 along the Y direction. The modular energy storage structure 200 can be inserted into the charging port 361 along the Y direction to achieve mechanical and electrical connection with the charging base 360. The charging port 361 is electrically connected to the modular energy storage structure 200, and a charging contact is provided inside the charging port 361 to form an electrical connection with the charging interface of the modular energy storage structure 200.

[0075] More specifically, the installation position of the charging base 360 ​​allows its charging port 361 to dock with the modular energy storage structure 200 that slides from the bracket 310. The arrangement of the charging port 361 facing the bracket 310 ensures that the modular energy storage structure 200 can smoothly enter the charging port 361 during its sliding along the bracket 310, achieving automatic docking.

[0076] In the specific implementation where the charging port 361 faces the bracket 310, the opening shape of the charging port 361 matches the outer contour of the modular energy storage structure 200, forming a guiding fit. The opening size of the charging port 361 is slightly larger than the corresponding size of the modular energy storage structure 200, reserving an appropriate assembly gap to facilitate the insertion and removal of the modular energy storage structure 200. The inner wall surface of the charging port 361 is provided with a guide slope or guide groove to guide the modular energy storage structure 200 to achieve precise positioning during insertion. The depth of the charging port 361 is determined according to the insertion length of the modular energy storage structure 200, ensuring that the modular energy storage structure 200 can form a stable connection with the charging base 360 ​​after being fully inserted.

[0077] During the implementation of the modular energy storage structure 200 being detachably inserted into the charging port 361 along the Y direction, the modular energy storage structure 200 slides along the receiving section 311A ​​of the bracket 310 under the pull of the connecting structure 370. When the modular energy storage structure 200 reaches the charging base 360, its front end aligns with the opening of the charging port 361. The modular energy storage structure 200 continues to move along the Y direction, gradually inserting into the charging port 361, with the outer wall of the modular energy storage structure 200 forming a sliding fit with the inner wall of the charging port 361. During insertion, the guide structure on the inner wall of the charging port 361 guides the modular energy storage structure 200 to achieve the correct insertion posture, avoiding jamming or deflection during insertion.

[0078] Once the modular energy storage structure 200 is fully inserted into the charging port 361, a detachable mechanical connection is formed between the modular energy storage structure 200 and the charging base 360. The charging port 361 is equipped with a locking device, such as a latch, locking pin, or clamping device, to secure the inserted modular energy storage structure 200 and prevent it from loosening due to vibration or external force during charging. The locking force of the locking device is moderate, ensuring both reliable connection and easy removal of the modular energy storage structure 200.

[0079] In the specific implementation of the electrical connection between charging port 361 and modular energy storage structure 200, charging port 361 is internally equipped with charging contacts, including positive and negative contacts. The charging contacts employ an elastic contact structure, such as a spring contact, elastic sheet, or spring pin, to ensure good electrical contact with the charging interface of modular energy storage structure 200. After the modular energy storage structure 200 is inserted into charging port 361, its charging interface automatically aligns with the charging contacts, establishing an electrical connection path. The charging contacts are connected to the charging power supply via wires, providing charging current to the modular energy storage structure 200.

[0080] During charging, the charging base 360 ​​monitors the charging status of the modular energy storage structure 200 through its charging contacts, including parameters such as voltage, current, and temperature. The charging base 360 ​​integrates a charging control circuit that adjusts the charging parameters according to the charging needs of the modular energy storage structure 200, achieving intelligent charging control. Once charging is complete, the charging base 360 ​​stops supplying power to the modular energy storage structure 200, preparing it for removal.

[0081] This embodiment achieves automatic docking and reliable connection between the charging base 360 ​​and the modular energy storage structure 200 by arranging the charging port 361 facing the bracket 310 and inserting the modular energy storage structure 200 along the Y direction. The guiding structure and locking device of the charging port 361 ensure smooth insertion and connection stability, while the elastic contact structure of the charging contacts ensures reliable electrical connection. Combined with the push-pull action of the battery swapping mechanism 300 in the aforementioned claims, the modular energy storage structure 200 can automatically insert into the charging port 361 for charging under the drive of the battery swapping mechanism 300, and automatically pull out and push it to the power supply end of the new energy construction equipment 10 after charging is completed. Compared with the manual plugging and unplugging charging method, the automatic plugging and unplugging charging method improves charging efficiency and operational safety, reduces manual intervention, realizes the automation and intelligence of the charging process of the modular energy storage structure 200, and provides reliable power guarantee for the continuous operation of the new energy construction equipment 10.

[0082] Please continue reading. Figure 1 And see Figure 6In an embodiment of the present invention, the modular energy storage structure 200 includes a frame 210 and an energy storage structure 220. The frame 210 is mounted outside the energy storage structure 220. The extension directions of both the frame 210 and the energy storage structure 220 are consistent with the extension direction of the support 310. The frame 210 is mounted outside the energy storage structure 220. Both ends of the energy storage structure 220 along its extension direction are provided with plugs 230. One plug 230 is used to electrically connect to the power supply end of the new energy construction equipment 10, and the other plug 230 is used to electrically connect to the charging base 360.

[0083] Specifically, the modular energy storage structure 200 includes a frame 210 and an energy storage structure 220. The frame 210 serves as the external protective shell of the modular energy storage structure 200, while the energy storage structure 220 serves as the core energy storage unit of the modular energy storage structure 200. The frame 210 surrounds the energy storage structure 220, providing mechanical protection and structural support. The extension directions of both the frame 210 and the energy storage structure 220 are consistent with the extension direction of the support 310. The major axis of both the frame 210 and the energy storage structure 220 extends along the Y direction, remaining parallel to the extension direction of the support 310. The energy storage structure 220 has plugs 230 at both ends along its extension direction, and electrical connection plugs 230 are provided at its two ends in the Y direction. One plug 230 is used for electrical connection to the power supply end of the new energy construction equipment 10, and the other plug 230 is used for electrical connection to the charging base 360.

[0084] More specifically, the external structure of the frame 210 matches the guide structure of the support 310, allowing the modular energy storage structure 200 to slide smoothly on the support 310. The arrangement of the frame 210 surrounding the energy storage structure 220 not only protects the internal energy storage structure 220 from external environmental influences but also provides the necessary structural strength for the modular energy storage structure 200 during transmission.

[0085] In the specific implementation where the frame 210 is installed outside the energy storage structure 220, the frame 210 is made of metal or high-strength engineering plastic material, possessing good mechanical strength and corrosion resistance. The internal space of the frame 210 is designed according to the external dimensions of the energy storage structure 220, with appropriate gaps reserved around the energy storage structure 220 for installing buffer pads, heat sinks, or protective layers. The outer wall of the frame 210 is provided with guide grooves or guide bosses that mate with the guide structure of the support 310, ensuring that the modular energy storage structure 200 maintains the correct movement trajectory when sliding on the support 310. The top and bottom of the frame 210 are provided with contact surfaces for the connecting structure 370 to contact, facilitating the push-pull operation of the modular energy storage structure 200 by the battery swapping mechanism 300.

[0086] The arrangement of both the frame 210 and the energy storage structure 220 extending in the same direction as the support 310 ensures that the geometry of the modular energy storage structure 200 perfectly matches the transmission path of the battery swapping system. The energy storage structure 220, as the core component of the modular energy storage structure 200, includes multiple battery cells, a battery management system, and internal wiring. The Y-direction extension of the energy storage structure 220 maximizes the use of the internal space of the frame 210, increasing energy storage density. Both ends of the energy storage structure 220 have pre-reserved installation spaces 101 for plugs 230, facilitating electrical connections.

[0087] In the specific implementation of the energy storage structure 220, plugs 230 are provided at both ends along its extension direction. The two plugs 230 are installed at the front and rear ends of the energy storage structure 220, respectively. The front plug 230 is a power supply plug 230, used to connect to the power supply end of the new energy construction equipment 10, and the rear plug 230 is a charging plug 230, used to connect to the charging base 360. The specifications and interface forms of the two plugs 230 are determined according to the corresponding connection objects. The current capacity of the power supply plug 230 is designed according to the power requirements of the new energy construction equipment 10, and the current capacity of the charging plug 230 is designed according to the charging power of the charging base 360. The installation position of the plugs 230 allows them to pass through the end face of the frame 210, forming an electrical connection with external equipment.

[0088] This embodiment achieves standardization and universality of the modular energy storage structure 200 through the integrated arrangement of the frame 210 and the energy storage structure 220, and the configuration of the plugs 230 at both ends. The frame 210 provides comprehensive protection for the energy storage structure 220, which in turn provides electrical support for the new energy construction equipment 10. The plugs 230 at both ends respectively realize power supply and charging functions. Combined with the push-pull operation of the battery swapping mechanism 300 and the plug-in function of the charging base 360 ​​in the aforementioned claims, the modular energy storage structure 200 can realize automated pickup, delivery, charging, and installation operations in the battery swapping system. The consistency of the extension direction of the frame 210 and the energy storage structure 220 with the extension direction of the support 310 ensures the stability and accuracy of the modular energy storage structure 200 during transmission. The symmetrical arrangement of the plugs 230 at both ends enables the modular energy storage structure 200 to have bidirectional connection capability, improving the flexibility and reliability of the system. Compared to traditional fixed energy storage methods, the modular energy storage structure 200's detachable features and standardized interfaces enable rapid replacement and flexible configuration of energy storage units, providing strong support for the continuity and efficiency of tunnel construction operations.

[0089] Please continue reading. Figure 1 and Figure 4In an embodiment of the present invention, the support 310 includes a bottom track 312B, a top track 311B, and a plurality of uprights 313. The plurality of uprights 313 are arranged at rectangular intervals along the Y direction. The top track 311B and the bottom track 312B both extend along the Y direction and are both disposed on one side of the new energy construction equipment 10. The top track 311B is spaced above the bottom track 312B. The end of the top track 311B facing away from the new energy construction equipment 10 is hinged to the upright 313. The top track 311B is inclined downward from the upright 313 towards the direction closer to the new energy construction equipment 10. The top track 311B forms a receiving section 311A, and the bottom track 312B forms a discharging section 312A. The bottom end of the top track 311B abuts against... On the bottom track 312B; when the battery swapping mechanism 300 is set in the discharge position 302 and in the initial position 304, the battery swapping mechanism 300 is used to connect with the modular energy storage structure 200, extend to the extended position 303 and reset to the initial position 304, so that the top track 311B is abutted by the top of the battery swapping mechanism 300 and rotates upward, so as to drive the modular energy storage structure 200 to slide along the support 310 through the discharge section 312A to the extended position 303 and be electrically connected to the power supply end of the new energy construction equipment 10. A buffer pad is provided at one end of the top track 311B that abuts against the bottom track 312B; a slider 240 adapted to the top track 311B or the bottom track 312B is provided at the bottom of the frame 210, and the slider 240 is slidably connected to the top track 311B or the bottom track 312B.

[0090] Specifically, the top track 311B, at one end away from the new energy construction equipment 10, is hinged to the upright 313. The end of the top track 311B furthest from the new energy construction equipment 10 is connected to the upright 313 via a hinged connection, forming a rotatable connection. The top track 311B is inclined downwards from the upright 313 towards the new energy construction equipment 10, starting from the hinge point and tilting downwards towards the new energy construction equipment 10. The top track 311B forms a receiving section 311A, and the bottom track 312B forms a discharging section 312A. The top track 311B receives the modular energy storage structure 200 to be charged, and the bottom track 312B discharges the charged modular energy storage structure 200. The bottom end of the top track 311B abuts against the bottom track 312B, and the lower end of the top track 311B forms contact support with the upper surface of the bottom track 312B.

[0091] More specifically, in the implementation of the top track 311B being hinged to the upright 313 at one end away from the new energy construction equipment 10, the hinge connection adopts the form of a hinge or a pivot, with the hinge axis perpendicular to the Y direction, allowing the top track 311B to rotate in the vertical plane. The position of the hinge point is determined according to the length and inclination angle of the top track 311B, ensuring that the top track 311B can naturally sag under its own weight and form contact with the bottom track 312B. Bearings or sliding bushings are provided at the hinge connection to reduce rotational friction and improve the rotational flexibility of the top track 311B.

[0092] The top-level track 311B, with its self-supporting pole 313 tilted downwards towards the new energy construction equipment 10, creates a certain angle that facilitates the downward sliding of the modular energy storage structure 200 along the track under gravity. The tilt angle is optimized based on the weight, friction coefficient, and required sliding speed of the modular energy storage structure 200, ensuring smooth sliding while preventing excessive impact from high speeds. The tilted arrangement of the top-level track 311B also facilitates the transition of the modular energy storage structure 200 from the receiving section 311A ​​to the discharge section 312A.

[0093] When the battery swapping mechanism 300 is positioned at the discharge position 302 and in the initial position 304, after connecting with the modular energy storage structure 200, the battery swapping mechanism 300 extends to the extended position 303 and then resets to the initial position 304. This causes the top rail 311B to be abutted against by the top of the battery swapping mechanism 300 and rotate upwards, thereby driving the modular energy storage structure 200 to slide along the support 310 through the discharge section 312A to the extended position 303 and electrically connect with the power supply end of the new energy construction equipment 10. When the battery swapping mechanism 300 is in the discharge position 302, during the extension of the multi-section telescopic rod 340, its top end contacts and pushes the top rail 311B to rotate upwards. The rotation of the top rail 311B causes the modular energy storage structure 200 on it to slide along the bottom rail 312B, and finally pushes it to the power supply end position of the new energy construction equipment 10.

[0094] A buffer pad is provided at one end of the top track 311B that abuts against the bottom track 312B. The buffer pad is made of rubber or elastic material at the contact position between the top track 311B and the bottom track 312B, and can absorb the impact energy when the top track 311B falls, reducing noise and vibration.

[0095] The bottom of the frame 210 is provided with a slider 240 adapted to the top track 311B or the bottom track 312B. The slider 240 is installed at the bottom of the frame 210 of the modular energy storage structure 200, and the shape and size of the slider 240 match the cross-sectional shape of the track. The slider 240 is slidably connected to the top track 311B or the bottom track 312B, and the slider 240 forms a sliding fit on the track, providing guidance and support for the movement of the modular energy storage structure 200 on the track.

[0096] This embodiment achieves the dual-layer transmission function and rotatable discharge function of the support 310 through the coordinated cooperation of the bottom track 312B, the top track 311B, and multiple uprights 313. The hinged arrangement and tilt angle of the top track 311B allow it to hang naturally under gravity and rotate upward under the push of the battery swapping mechanism 300, realizing the automatic discharge of the modular energy storage structure 200. The bottom track 312B provides a stable sliding base, and the rotation function of the top track 311B increases the flexibility of the discharge process. Combined with the lifting and telescopic actions of the battery swapping mechanism 300 in the preceding claims, the dual-layer structure of the support 310 and the battery swapping mechanism 300 form an effective cooperation. At the receiving position 301, the modular energy storage structure 200 slides in along the top track 311B, and at the discharge position 302, it slides out along the bottom track 312B through the rotation of the top track 311B. The sliding connection between the slider 240 and the track ensures the stability and accuracy of the modular energy storage structure 200 during transmission, and the buffer pad reduces the impact and noise during operation. Compared to a single-layer track structure, a double-layer rotatable track structure improves the space utilization and transmission efficiency of the battery swapping system, separates the receiving and discharging functions, avoids interference between modular energy storage structures 200 in different states, and provides a reliable structural foundation for continuous battery swapping operations.

[0097] The above description is merely an exemplary embodiment of the present invention and does not limit the scope of protection of the present invention. Any equivalent structural transformations made based on the technical concept of the present invention and the contents of the specification and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present invention.
