Description

Technical Field

[0001] This invention relates to the field of mobile energy storage technology, specifically a mobile energy storage device. Background Technology

[0002] Mobile energy storage devices typically refer to integrated power systems with built-in high-capacity rechargeable batteries (such as lithium-ion batteries), AC / DC input / output capabilities, and easy portability. They are widely used in various scenarios such as outdoor activities, emergency preparedness, off-grid operations, and mobile device charging, providing users with portable, stable, and high-power power. With the diversification of electrical equipment and the growth of power demands, the reliability, safety, and durability of the output interface of mobile energy storage devices have become core performance indicators.

[0003] Currently, the electrical connection between mobile energy storage devices and external electrical equipment generally adopts a method of directly plugging in standardized sockets (such as AC sockets, DC 5521 ports, USB ports, etc.) and corresponding plugs. That is, the connection between devices is achieved by plugging and unplugging the plug. Existing plugs and sockets mostly use material deformation to form a relatively stable connection.

[0004] Because there is a certain size difference between the plug and the socket, this helps to improve the stability between the plug and the socket after the device is connected; however, it also increases the difficulty of plugging and unplugging, and it is easy for the plug to not be fully inserted into the socket, but the internal electrodes of the two are connected (lack of connection). This forms a loose, high-resistance electrical contact. In this state, the current flowing through the high contact resistance area will generate a lot of Joule heat, causing the contact point temperature to rise sharply, which may cause the insulation material to age, melt, or even catch fire. Moreover, the extra resistance at the lack of connection will waste electrical energy, reduce output efficiency, and cause abnormal drop in output voltage when operating at high current, affecting the normal operation of the electrical equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a mobile energy storage device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A mobile energy storage device includes an energy storage module, on which a connecting frame is rotatably connected via a steering component; It also includes a sliding frame that is slidably connected to the connecting frame via a buffer, a fixing plate is mounted on the sliding frame, a stationary contact is mounted on one side of the fixing plate, a connector is mounted on the other side, and a contact head that is in communication with the stationary contact is installed inside the connector. The sliding frame is provided with a guide, which includes a moving contact that cooperates with the stationary contact and a locking member for limiting the movement of the moving contact. The connector is provided with a protective component for protecting the contact head, the protective component including a protective plate that slides and fits into the connector; During the connection of the electrical equipment with the energy storage module, the protective plate can slide inward in the connector to increase the exposed length of the contact head; and after the connection is in place, the locking member can release the limiting state to drive the conducting member to move, thereby driving the moving contact to approach and abut against the stationary contact.

[0007] The mobile energy storage device described above includes a sliding plate that is slidably fitted with the sliding frame, a movable contact that is slidably fitted with the sliding plate, a retaining spring wrapped around the movable contact, the two ends of the retaining spring abutting against the sliding plate and the movable contact respectively, and a pushing spring provided inside the sliding frame, the two ends of the pushing spring abutting against the sliding plate and the sliding frame respectively.

[0009] The mobile energy storage device as described above: the protective component includes a protective baffle installed on the connector, the protective baffle being disposed between multiple sets of contact heads; a return spring is disposed inside the connector; the two ends of the return spring abut against the protective plate and the protective baffle respectively.

[0010] The mobile energy storage device described above includes: a trigger frame slidably fitted onto the sliding frame; a slide rod slidably fitted onto the trigger frame and slidingly fitted onto the sliding plate; a reset baffle abutting against the sliding plate at one end of the slide rod; a trigger wedge slidably fitted onto the trigger frame; a trigger spring provided on the trigger frame; and both ends of the trigger spring abutting against the trigger wedge and the trigger frame, respectively. The trigger wedge engages with the locking groove.

[0011] As described above, in the mobile energy storage device: the trigger wedge is inclined at one end away from the fixed plate, and its back side is parallel to the fixed plate; the spring constant of the trigger spring is greater than that of the locking spring; initially, the trigger wedge and the locking wedge are misaligned; during the connection process between the electrical equipment and the energy storage module, the trigger wedge gradually approaches the locking groove, and when connected in place, the trigger wedge and the locking groove are aligned; the trigger wedge can enter the locking groove under the elastic force of the trigger spring and push the locking wedge to move, so as to disengage it from the locking groove.

[0012] The mobile energy storage device described above: a slot is provided on the trigger frame, a transmission wedge block that is slidably connected to the sliding frame is slidably fitted into the slot, a follower block is installed on the protective plate, the follower block cooperates with the transmission wedge block, an inclined rod that cooperates with the transmission wedge block is installed on the trigger frame, a compression spring is provided on the inclined rod, and the two ends of the compression spring abut against the inclined rod and the connecting frame respectively.

[0013] As described above, in the mobile energy storage device: the transmission wedge is inclined on the side away from the sliding plate, and the inclined rod is inclined; its inclination direction is along the axis of the sliding frame pointing towards the sliding plate, and the distance between the inclined rod and the trigger frame gradually increases.

[0014] The mobile energy storage device described above includes: a buffer component comprising a guide post mounted on the connecting frame; a connecting sleeve slidably fitted with the guide post is mounted on the sliding frame; multiple sets of buffer springs are sleeved on the guide post; the buffer springs are respectively mounted on both sides of the connecting sleeve, and the two ends of the buffer springs abut against the connecting sleeve and the connecting frame respectively.

[0015] The mobile energy storage device as described above: the steering component includes a movable turntable mounted on the connecting frame; multiple sets of movable toothed blocks are mounted on the movable turntable; the movable toothed blocks are equidistantly arranged along the circumference of the movable turntable; a guide rail is mounted on the energy storage module, and a stationary turntable is slidably fitted onto the guide rail; multiple sets of stationary toothed blocks are mounted on the stationary turntable, the stationary toothed blocks are equidistantly arranged along the circumference of the stationary turntable, the stationary toothed blocks mesh with the movable toothed blocks, a limiting spring is sleeved on the guide rail, and the two ends of the limiting spring abut against the guide rail and the stationary turntable respectively; both the stationary toothed blocks and the movable toothed blocks are sharp.

[0016] Compared with the prior art, the beneficial effects of the present invention are: In the non-connected state, the locking component mechanically locks the conducting component, ensuring that the moving contact and the stationary contact are physically separated. This effectively prevents the energy storage module (such as a secondary battery) from being accidentally discharged or short-circuited inside the output port due to vibration, accidental contact, or other reasons during storage or transportation. In other words, it cuts off the internal circuit of the output terminal, preventing the energy storage module from being accidentally discharged or short-circuited at the port. The protective component initially partially shields the contacts inside the connector, which not only prevents dust, impurities and other foreign objects from entering the socket and causing pollution or blockage, but also directly prevents accidental contact with live ports by human fingers or handheld metal objects, providing basic personal safety protection. In addition, the protective baffle forms physical isolation between multiple sets of contacts, significantly increasing the creepage distance and electrical clearance between each electrode, effectively suppressing leakage or even short circuits between electrodes caused by condensation or dust accumulation in humid environments, and improving the adaptability and safety of the device in complex environments. The power generated by the connection drives the protective component to move, thereby driving the locking component to release the limit. At this time, the conductive component drives the moving contact to contact the stationary contact, realizing a stable electrical connection. That is, only when the external connector is fully and correctly inserted into the connector and pushes the protective plate to the set position can the subsequent unlocking and power-on process be triggered. This can avoid the electrical equipment and energy storage equipment from being loosely connected, thereby avoiding the safety hazards that may be caused by loose connections, such as high temperature, arcing, energy loss, or even melting of the connection point, and ensuring the high efficiency and stability of power transmission. By absorbing the impact of insertion and extraction forces through the buffer, the instantaneous impact and vibration transmitted to the connecting frame and even the entire energy storage module are reduced. This effectively avoids mechanical damage to the internal precision conductive parts, locking parts and electrical connection parts caused by rough insertion and extraction or accidental collisions, thereby improving the reliability and service life of the device. In addition, during power supply, the buffer can also absorb slight pulling or vibration from the connecting cables, preventing these interferences from being directly converted into hard displacement of the sliding frame, which helps to maintain the stability of the electrical connection.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0021] Please see Figure 1-12As an embodiment of the present invention, the mobile energy storage device includes an energy storage module 1, and a connecting frame 2 is rotatably connected to the energy storage module 1 via a steering component. It also includes a sliding frame 6 that is slidably connected to the connecting frame 2 via a buffer. A fixing plate 8 is installed on the sliding frame 6. A stationary contact 801 is installed on one side of the fixing plate 8, and a connector 9 is installed on the other side. A contact head 901 that is in communication with the stationary contact 801 is installed inside the connector 9. The sliding frame 6 is provided with a conductive element, which includes a movable contact 15 that cooperates with the stationary contact 801 and a locking element for limiting the movable contact 15. The connector 9 is provided with a protective component for protecting the contact head 901. The protective component includes a protective plate 10 that slides and fits into the connector 9. During the connection of the electrical equipment with the energy storage module 1, the protective plate 10 can slide inward in the connector 9 to increase the exposed length of the contact head 901; and after the connection is in place, the locking member can release the limiting state to drive the conducting member to move, thereby driving the moving contact 15 to approach and abut against the stationary contact 801.

[0022] In this embodiment, in the initial state, the locking member locks the moving contact 15 (which is electrically connected to the energy storage module 1), thereby keeping the moving contact 15 separated from the stationary contact 801. This prevents damage to the energy storage device due to accidental short circuits between multiple contact heads 901 when not in use, thus improving the safety of the device. Furthermore, in the initial state, the protective plate 10 is located away from the fixed plate 8, resulting in a relatively short exposed length of the contact head 901. The protective member effectively reduces the possibility of the contact head 901 coming into contact with external objects, thereby reducing the likelihood of deformation due to impact, and thus improving the practicality and service life of the device.

[0023] During the connection process between the connector of the charging device or the electrical device and the connector 9 (the connector and the connector 9 are slidably connected, and the connector is inserted into the connector 9. Through the deformation of the materials of the two, a stable connection can be formed), the connector will squeeze the protective plate 10 and drive the protective plate 10 to slide inward in the connector 9, thereby increasing the exposed length of the contact head 901 and forming a stable electrical connection with the connector.

[0024] When the connector is fully inserted into the connector 9, the protective plate 10 moves to the set position. At this time, the protective plate 10 can drive the locking member to release the locking state, thereby driving the moving contact 15 to quickly approach and contact the stationary contact 801 through the conductive member. At this time, the energy storage module 1 (such as a secondary battery) can supply power to the electrical device or the charging device can charge the energy storage module 1. That is, only when the external connector is fully and correctly inserted into the connector 9 and pushes the protective plate 10 to the set position can the subsequent unlocking and power-on process be triggered. This can avoid the electrical device and the energy storage device from being loosely connected, thereby avoiding the safety hazards such as high temperature, arcing, energy loss or even melting of the connection point that may be caused by the loose connection, and ensuring the high efficiency and stability of power transmission.

[0025] After the power is used, the connector separates from the connector 9. During this process, the protective component resets to continue to perform the protective action, while the conductive component resets and is limited by the locking component to maintain the separation state of the moving contact 15 and the stationary contact 801, so as to improve the stability and safety of energy storage equipment storage and transportation.

[0026] During power supply, the connecting frame 2 can rotate due to the steering action of the steering component, thereby preventing the moving electrical equipment from pulling on the connecting component and causing the connecting circuit to twist, thus improving the practicality of the energy storage device.

[0027] Furthermore, during the insertion and removal of connectors, the impact of mechanical kinetic energy on the energy storage device can be reduced by the buffering effect of the buffer.

[0028] As a further embodiment of the present invention, the conductive member further includes a sliding plate 12 that is slidably fitted with the sliding frame 6, the movable contact 15 being slidably fitted with the sliding plate 12, a retaining spring 16 being wrapped around the movable contact 15, the two ends of the retaining spring 16 being abutted against the sliding plate 12 and the movable contact 15 respectively, and a pushing spring 17 being provided inside the sliding frame 6, the two ends of the pushing spring 17 being abutted against the sliding plate 12 and the sliding frame 6 respectively.

[0029] In this embodiment, in the initial state, the locking member limits the sliding plate 12, the push spring 17 is in a compressed state, the moving contact 15 is separated from the stationary contact 801, and the connector 9 is in an open circuit state with the energy storage module 1.

[0030] When the connector of an external device (such as a charging device) is fully inserted into the connector 9 and the protective plate 10 is pushed to the set position, the protective plate 10 can release the locking state of the locking member. After the lock is released, the pre-compressed push spring 17 quickly releases its elastic force, pushing the sliding plate 12 and the moving contact (15) mounted on it to slide rapidly towards the fixed plate (8), so that the moving contact (15) contacts the stationary contact 801. At the moment of contact, the clamping spring 16 can further provide buffering and continuous clamping force to ensure that a tight and stable electrical connection is formed between the moving contact 15 and the stationary contact 801, thereby reliably guiding the electrical energy of the energy storage module 1 to the contact head 901 to supply power to the external electrical equipment.

[0031] Only when the external connector is fully and correctly inserted into the connector 9 and the protective plate 10 is pushed to the set position can the subsequent unlocking and power-on process be triggered; this can avoid the electrical equipment and energy storage equipment from being loosely connected, thereby avoiding the safety hazards that may be caused by loose connections, such as high temperature, arcing, energy loss or even melting of connection points, and ensuring the high efficiency and stability of power transmission.

[0032] As a further embodiment of the present invention, the locking member includes a locking wedge 13 that slides and engages with the sliding plate 12, and a locking spring 14 is provided inside the sliding plate 12. The two ends of the locking spring 14 abut against the locking wedge 13 and the sliding plate 12 respectively. The sliding frame 6 is provided with a locking groove 602 that cooperates with the locking wedge 13.

[0033] In this embodiment, in the initial state, under the elastic force of the locking spring 14, a portion of the locking wedge 13 engages in the locking groove 602 on the sliding frame 6, thereby firmly locking the sliding plate 12 and its moving contact 15 in the initial separated position. At this time, the push spring 17 is compressed and stored energy, and the entire circuit is in the open state, achieving safety interlocking.

[0034] When the connector of an external electrical device (such as a charging device) is fully inserted into the connector 9 and the protective plate 10 is pushed to the set position, the locking wedge 13 can be driven to retract into the sliding plate 12 against the elastic force of the locking spring 14, thereby completely disengaging it from the locking groove 602.

[0035] Once the locking wedge 13 disengages from the locking groove 602, the locking of the sliding plate 12 is released. Subsequently, the compressed push spring 17 quickly releases its elastic force, pushing the sliding plate 12, along with the moving contact 15, rapidly towards the fixed plate 8, completing the final connection of the electrical connection. The locking mechanism ensures that the circuit connection action has a clear mechanical triggering condition and rapid response, and its structure is simple and reliable.

[0036] As a further embodiment of the present invention, the protective component includes a protective baffle 902 installed on the connector 9, the protective baffle 902 being disposed between multiple sets of contact heads 901; a return spring 11 is disposed inside the connector 9; the two ends of the return spring 11 abut against the protective plate 10 and the protective baffle 902 respectively.

[0037] In this embodiment, in the initial state, under the action of the return spring 11, the protective plate 10 extends out of the port of the connector 9, which can effectively prevent dust and foreign objects from entering the interior of the connector 9, and also prevent people or tools from accidentally touching the live contact head 901, thus improving safety. The protective baffle 902 set between multiple groups of contact heads 901 further increases the creepage distance and electrical isolation between each contact head 901, preventing short circuits between contact heads 901 due to condensation, dirt, etc.

[0038] When the external connector is inserted into the connector 9, the end of the connector first contacts and presses against the protective plate 10, pushing the protective plate 10 to slide inward into the connector 9 against the elastic force of the return spring 11. During this process, the protective plate 10 gradually retracts, and the contact head 901 it protects gradually becomes exposed until it finally makes reliable contact with the fully inserted connector. The protective baffle 902 remains stationary, providing stable guidance and support for the sliding protective plate 10, and serving as a reliable support for one end of the return spring 11.

[0039] When the connector is pulled out, the restoring force of the return spring 11 pushes the protective plate 10 to automatically return to its initial extended position, re-covering the contact head 901 and achieving continuous protection. In other words, without additional user intervention, it automatically achieves the function of exposing the connector during insertion and protecting it during removal, improving the equipment's protection level and ease of use.

[0040] As a further embodiment of the present invention, a trigger frame 18 is slidably fitted onto the sliding frame 6, and a slide rod 19 is mounted on the trigger frame 18 that is slidably fitted onto the sliding plate 12. A reset baffle 1901 that abuts against the sliding plate 12 is mounted on one end of the slide rod 19. A trigger wedge 24 is slidably fitted onto the trigger frame 18, and a trigger spring 23 is provided on the trigger frame 18. Both ends of the trigger spring 23 abut against the trigger wedge 24 and the trigger frame 18, respectively. The trigger wedge 24 cooperates with the locking groove 602.

[0041] As a further embodiment of the present invention, the trigger wedge 24 is inclined at one end away from the fixing plate 8, and its back side is parallel to the fixing plate 8; the spring constant of the trigger spring 23 is greater than that of the locking spring 14. In the initial state, the trigger wedge 24 and the locking wedge 13 are misaligned. During the connection process between the electrical equipment and the energy storage module 1, the trigger wedge 24 gradually approaches the locking groove 602, and when connected in place, the trigger wedge 24 is aligned with the locking groove 602; the trigger wedge 24 can enter the locking groove 602 under the elastic force of the trigger spring 23, and push the locking wedge 13 to move so that it disengages from the locking groove 602.

[0042] In this embodiment, in the initial state, the trigger wedge 24 tends to pop outward under the preload of the trigger spring 23, but because it is axially misaligned with the locking wedge 13 and the locking groove 602, it is restricted within the trigger frame 18 and cannot pop out.

[0043] When the external connector is inserted and pushes the protective plate 10 inward, the protective plate 10 drives the entire trigger frame 18 to slide along the sliding frame 6 toward the fixed plate 8. During this process, the slide rod 19 and the reset baffle 1901 fixed on the trigger frame 18 move together, and the reset baffle 1901 gradually separates from the sliding plate 12.

[0044] When the connector is fully inserted and the protective plate 10 reaches the final set position, the trigger frame 18 also moves to the corresponding position, so that the trigger wedge 24 is completely aligned with the locking groove 602 in the axial direction. At this time, since the alignment releases the radial constraint, the long-stored trigger spring 23 quickly pops the trigger wedge 24 outward, so that it is embedded in the locking groove 602.

[0045] Since the spring constant of the trigger spring 23 is greater than that of the locking spring 14, the thrust it generates is sufficient to overcome the elastic force of the locking spring 14. Therefore, the continuously inserted trigger wedge 24 completely pushes the locking wedge 13 out of the locking groove 602 and retracts it into the sliding plate 12, thereby releasing the locking of the sliding plate 12, and triggering the push spring 17 to push the moving contact 15 to quickly connect the circuit. At this time, the sliding plate 12 abuts against the reset baffle 1901.

[0046] During the reset process of the protective plate 10, the trigger frame 18 can move in the opposite direction (due to the squeezing action between the inclined surface of the trigger wedge 24 and the wall of the locking groove 602, the trigger wedge 24 re-enters the trigger frame 18, and the trigger spring 23 is compressed), thereby driving the sliding plate 12 to reset through the reset baffle 1901 until the locking member limits the conduction member again.

[0047] Only when the external connector is fully and correctly inserted into the connector 9 and the protective plate 10 is pushed to the set position can the subsequent unlocking and power-on process be triggered; this can avoid the electrical equipment and energy storage equipment from being loosely connected, thereby avoiding the safety hazards that may be caused by loose connections, such as high temperature, arcing, energy loss or even melting of connection points, and ensuring the high efficiency and stability of power transmission.

[0048] As a further embodiment of the present invention, the trigger frame 18 is provided with a slot 1801, and a transmission wedge 22 that is slidably connected to the sliding frame 6 is slidably fitted into the slot 1801. A follower block 1001 is installed on the protective plate 10, and the follower block 1001 cooperates with the transmission wedge 22. A diagonal rod 20 that cooperates with the transmission wedge 22 is installed on the trigger frame 18. A compression spring 21 is provided on the diagonal rod 20, and the two ends of the compression spring 21 abut against the diagonal rod 20 and the connecting frame 2, respectively.

[0049] As a further embodiment of the present invention, the transmission wedge 22 is inclined on the side away from the sliding plate 12, and the inclined rod 20 is inclined; its inclination direction is: along the axis of the sliding frame 6 pointing towards the sliding plate 12, and the distance between the inclined rod 20 and the trigger frame 18 gradually increases.

[0050] In this embodiment, the initial state is as follows: the inclined rod 20 is in contact with the transmission wedge 22, and the transmission wedge 22 is in contact with the follower block 1001.

[0051] Insertion and Transmission: When the external connector is inserted into the connector 9, its end pushes the protective plate 10 to slide inward. The follower block 1001 on the protective plate 10 moves accordingly and begins to contact the inclined surface of the transmission wedge block 22. Since the transmission wedge block 22 is slidably connected to the sliding frame 6, its axial movement is constrained. Therefore, the force applied by the follower block 1001 can push the transmission wedge block 22 radially away from the connector 9 along the sliding frame 6.

[0052] Motion conversion: When the transmission wedge 22 slides, it always maintains contact with the inclined surface of the inclined rod 20. Since the inclination direction of the inclined rod 20 is set to "point from the axis of the sliding frame (6) to the direction of the sliding plate 12, the distance between the inclined rod 20 and the trigger frame 18 gradually increases", that is, the transmission wedge 22 pushes the entire trigger frame 18 to move through the inclined rod 20, and compresses the compression spring 21 (the trigger frame 18 moves closer to the fixed plate 8).

[0053] Position triggering: When the connector is fully inserted and the protective plate 10 reaches the final set position, the follower block 1001 pushes the transmission wedge block 22 to its limit position. At this time, the trigger frame 18 is pushed to the predetermined position under the linkage of the transmission wedge block 22 and the inclined rod 20, so that the trigger wedge block 24 installed on it is precisely aligned axially with the locking groove 602 on the sliding frame 6.

[0054] The linear insertion of the protective plate 10 is reliably converted into the linear movement of the trigger frame 18 via a ramp mechanism consisting of the follower block 1001, the transmission wedge block 22, and the ramp 20. This ensures that the trigger frame 18 can only move to the position where the trigger wedge block 24 aligns with the locking groove 602 when the external plug is fully inserted (the protective plate 10 is in position). This strictly guarantees the hardware foundation of the safety principle that the necessary mechanical prerequisite for electrical connection (full connection first, then circuit conduction) must be met. The compression spring 21 provides a restoring force to the ramp 20 and assists in the reset of the entire structure when the connector is pulled out.

[0055] As a further embodiment of the present invention, the buffer includes a guide post 201 mounted on the connecting frame 2; a connecting sleeve 601 that slidably engages with the guide post 201 is mounted on the sliding frame 6, and multiple sets of buffer springs 7 are sleeved on the guide post 201. The buffer springs 7 are respectively mounted on both sides of the connecting sleeve 601, and the two ends of the buffer springs 7 abut against the connecting sleeve 601 and the connecting frame 2, respectively.

[0056] In this embodiment, the sliding engagement of the guide post 201 and the connecting sleeve 601 provides precise linear motion guidance for the sliding frame 6 and the fixed plate 8, connector 9 and other components mounted on it, ensuring that they move smoothly along the predetermined axis during insertion and removal, and avoiding deviation or jamming.

[0057] In the initial (non-plugging) state, the preload of multiple sets of buffer springs 7 keeps the entire sliding frame 6 assembly in a balanced intermediate position in the axial direction.

[0058] When the connector of an external electrical device is inserted into or removed from the connector 9, the axial force acting on the connector 9 is transmitted to the connecting sleeve 601 through the sliding frame 6, thereby compressing the buffer spring 7 located on one side of the force direction. At the same time, the buffer spring 7 on the other side is stretched. In this process, the impactful insertion and extraction force is quickly converted into the elastic potential energy of the buffer spring 7, which is absorbed and released through the compression and rebound of the spring, thereby reducing the instantaneous impact and vibration transmitted to the connecting frame 2 and even the entire energy storage module 1; effectively avoiding mechanical damage to the internal precision conductive parts, locking parts and electrical connection parts caused by rough insertion and extraction or accidental collision, improving the reliability and service life of the device; and during the power supply process, the buffer spring 7 can also absorb the slight pulling or vibration from the connecting cable, preventing these interferences from being directly converted into the hard displacement of the sliding frame 6, which helps to maintain the stability of the electrical connection.

[0059] As a further embodiment of the present invention, the steering component includes a movable turntable 3 mounted on the connecting frame 2; multiple sets of movable tooth blocks 301 are mounted on the movable turntable 3; the movable tooth blocks 301 are equidistantly arranged along the circumference of the movable turntable 3; a guide rail 101 is mounted on the energy storage module 1, and a stationary turntable 4 is slidably fitted on the guide rail 101; multiple sets of stationary tooth blocks 401 are mounted on the stationary turntable 4, the stationary tooth blocks 401 are equidistantly arranged along the circumference of the stationary turntable 4, the stationary tooth blocks 401 mesh with the movable tooth blocks 301, a limiting spring 5 is sleeved on the guide rail 101, and the two ends of the limiting spring 5 abut against the guide rail 101 and the stationary turntable 4 respectively; both the stationary tooth blocks 401 and the movable tooth blocks 301 are sharp.

[0060] In this embodiment, in the initial state: under the preload of the limiting spring 5, the stationary turntable 4 is pressed against the moving turntable 3, causing the two sets of sharp-shaped stationary tooth blocks 401 and moving tooth blocks 301 to mesh with each other, forming a circumferential lock. At this time, the connecting frame 2 is fixed and will not rotate freely, ensuring the stability of the equipment during stationary or moving processes.

[0061] Working (slippage and steering) state: When the connection cable of the external electrical equipment is dragged or twisted due to the movement of the equipment, a torsional torque is generated on the connected frame 2. This torque is transmitted to the moving turntable 3 and its moving tooth block 301.

[0062] When the torque is less than the set value: the meshing friction between the stationary tooth block 401 and the moving tooth block 301 (generated by the preload of the limit spring 5) is sufficient to resist the torque, the tooth blocks remain engaged, the connecting frame 2 does not rotate, and avoids random shaking caused by slight disturbances.

[0063] When the torque exceeds the set value: When the torsional torque increases sufficiently to overcome the resistance formed by the meshing friction between the tooth blocks and the pressure of the limiting spring 5, the sharp inclined surface of the tooth blocks will generate an axial component force that separates the two. This component force pushes the stationary turntable 4 to compress the limiting spring 5 and slide backward along the guide rail 101, thereby disengaging the stationary tooth block 401 from the moving tooth block 301. Once disengaged, the connecting frame 2 can rotate freely under the drive of the moving turntable 3, releasing the torque in the cable.

[0064] Reset: When the torsional force decreases or disappears, under the restoring force of the limit spring 5, the stationary turntable 4 is pushed back, and the stationary tooth block 401 on it is automatically located and re-engaged with the moving tooth block 301 on the moving turntable 3 under the guidance of the spring force and the sharp inclined surface of the tooth block, thus restoring circumferential locking.

[0065] The steering mechanism effectively avoids the problem of excessive twisting, knotting, or even damage to connecting cables caused by the movement of electrical equipment, thus improving safety and convenience in dynamic usage scenarios. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0066] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
