Description

Technical Field

[0001] The present invention relates to the field of hybrid energy storage, and in particular to a movable hybrid energy storage device. Background Art

[0002] Hybrid energy storage systems combine the advantages of different energy storage technologies, such as the high energy density of batteries and the high power density of supercapacitors, to achieve a more efficient and reliable energy storage solution. Traditional hybrid energy storage devices are not convenient to move due to their large size, heavy weight, complex installation, inconvenient transportation, and dependence on the environment, which limits their application in situations that require rapid deployment and flexible use. In addition, current hybrid energy storage devices are powered by plugging the power cord directly into their mobile power supplies. However, the plug and the socket on the mobile power supply are snapped together. When the staff operates the tool for construction, once the staff's operating range exceeds the length of the tool cord, the plug will be pulled, causing the plug to loosen or even separate from the power socket, posing a certain risk of leakage.

[0003] The currently disclosed Chinese patent CN219499045U discloses an energy storage device that is easy to move and place, including a mounting frame with multiple mounting positions, an electric energy storage box is arranged on the mounting position of the mounting frame, and a mobile housing is fixedly connected to the bottom of the mounting frame, and a mobile mechanism is arranged inside the mobile housing. When the device is not moved, the above patent limits the movement of the entire device through a retractable friction plate to achieve a balancing effect without tipping over. However, the locking mechanism may fail on different ground surfaces due to changes in friction, causing the device to slide when it should not move.

[0004] There is also a Chinese patent application with publication number CN116260009A: A multifunctional emergency power supply device, including an emergency power supply mobile power supply body and a tool wire plug body, a movable pull rod is fixedly installed in the middle of the emergency power supply mobile power supply body, a movable roller is movably installed at the bottom of the emergency power supply mobile power supply body, a buzzer alarm is fixedly installed on the top of the emergency power supply mobile power supply body, a control terminal is fixedly installed on the left side of the emergency power supply mobile power supply body, an anti-dropping induction component is fixedly installed on the top of the emergency power supply mobile power supply body, and a sealing component is fixedly installed on the left side of the emergency power supply mobile power supply body. The above patent inserts the wire plug body into the hybrid energy storage mobile power supply body, and then flips the movable rotating plate so that the anti-dropping plug plate just catches the plug of the limit wire plug body. However, this method requires manually flipping the movable rotating plate and ensuring that the anti-dropping plug plate correctly catches the plug, which increases the operation steps and time, and if the card connection is not in place, it will also cause the plug to fall off.

[0005] In addition, although there are some devices that can lock plugs in the prior art, they are either inconvenient to operate or have complex structures, and cannot be adaptively locked according to the insertion status of the plug, and are inconvenient to unlock. Therefore, there is a need for a portable hybrid energy storage device that can automatically lock and unlock the plug at the socket, and can adaptively adjust the supporting force according to the ground material to ensure stable power supply. Summary of the invention

[0006] In view of the problems existing in the prior art, a portable hybrid energy storage device is provided. The present invention automatically activates a trigger driver when an energy storage power source is turned on through the linkage between a trigger member and a card connector, thereby driving the trigger member to push the card connector, so that the edge of the plug is restricted between the card connector and the socket, avoiding the risk of power outage due to loosening or falling off of the plug.

[0008] Preferably, a slot for the trigger member to slide in is provided on the guide housing along the direction in which the plug is inserted, and a slide groove for the card connector to slide in is provided on the guide housing along a direction perpendicular to the slot. When the trigger member pushes all the card connectors synchronously, each card connector moves toward the center of the guide housing, so that the plug is gradually in a fixed state confined between the card connector and the socket.

[0009] Preferably, the clamping member is a block structure, the triggering member is a ring structure, the clamping member has a chamfer on one side edge facing the triggering member, the inner side of the triggering member has an inclined groove that matches the chamfer of the clamping member, and when the triggering member applies pressure to the clamping member along the chamfer of the clamping member through the inclined groove, the clamping member is in a moving state gradually approaching the center of the guide bin body.

[0010] Preferably, a rubber pad capable of adapting to the edge of the plug is fixedly provided on the surface of the clamping member in contact with the plug. When the rubber pad contacts the edge of the plug, the rubber pad is in a pressure state to press the plug toward the socket.

[0011] Preferably, the guide bin body is composed of an inner ring and an outer ring, and a plurality of balls are provided between the inner side of the trigger member and the inner ring and between the outer side and the outer ring in the circumferential direction around the outer ring. The trigger member is provided with grooves for the balls to be embedded therein, and the inner ring and the outer ring are provided with guide grooves along their axial directions for rolling contact with the balls.

[0012] Preferably, the outer ring has a rib for limiting the movement range of the trigger member. When the end of the trigger member contacts the rib, the clamping member and the trigger member are in a completely staggered state, and the plug is firmly pressed against the socket by the clamping member.

[0013] Preferably, the first reset connector and the second reset connector are both tension springs, and when the trigger member pushes the clamping member, the first reset connector and the second reset connector are both in a stretched state.

[0014] Preferably, the trigger member is provided with an avoidance groove for avoiding the second reset connector during the process of pushing the clamping member.

[0015] Preferably, the trigger driver has a fixed magnet and a movable magnet, the fixed magnet is fixedly connected to the guide bin body, the movable magnet is fixedly connected to the trigger member, the fixed magnet and the movable magnet are both electromagnets, and when the trigger driver is not powered on, the movable magnet is located at a position in the guide bin body where it contacts the fixed magnet.

[0016] Preferably, the mobile frame is provided with support components on all four sides for keeping the mobile frame stable when the energy storage power source is not moved, the support components include a support rod and a guide cylinder mounted on the support rod and fixed to the mobile frame, and a downward drive for driving all the support rods to move vertically downward, and the lower end of the support rod has an anti-slip portion for maintaining friction with the ground.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention uses an anti-dropping component to automatically fix the plug after it is inserted into the socket, greatly reducing the risk of power outages caused by loosening or falling off of the plug. That is, through the linkage mechanism of the clip and the trigger, after the energy storage power supply is turned on, the trigger driver automatically controls the trigger to push all the clips, so that all the clips are synchronously moved toward the plug, thereby restricting the plug between the clip and the socket, ensuring the fixing effect of the plug, and maintaining stability even during movement. After the energy storage power supply is turned off, the clip and the trigger are automatically reset with the action of the first reset connector and the second reset connector, thereby releasing the fixed state of the plug, making it convenient for users to pull out, avoiding the trouble of manual unlocking and potential safety hazards, and improving the user experience.

[0019] 2. The present invention activates the trigger member by triggering the driver, so that it slides along the slot and contacts the card connector. With the cooperation of the inclined groove and the chamfer, the trigger member applies gradually increasing pressure to the card connector, pushing the card connector to move along the slide groove toward the center of the guide bin body. As the rubber pad on the surface of the card connector gradually approaches and fits the edge of the plug, the rubber pad naturally adapts to plugs of different shapes and sizes due to its elastic properties, and applies a pressure toward the socket, thereby increasing the tightness and fixing stability between the plug and the socket. As all the card connectors move synchronously, it is ensured that the plug is evenly confined between the card connector and the socket, and will not fall off easily even if subjected to external force, thereby ensuring the safety and reliability of the plug connection.

[0020] 3. The present invention evenly distributes support rods around the mobile frame. As the downward drive drives all the support rods to support on the ground, the stability and balance of the mobile frame are ensured. The friction between the anti-slip portion at the lower end of the support rod and the ground effectively prevents the mobile frame from accidentally moving or tilting, thereby improving the overall stability and thus improving the stability of the energy storage power supply.

DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] See also Figure 1-Figure 7As shown, a movable hybrid energy storage device is applied to an energy storage power supply, comprising a movable frame 1 and an energy storage cabinet 2 arranged therein for storing the energy storage power supply, wherein a universal wheel 11 having a brake pad 111 is arranged at each of the four corners at the bottom of the movable frame 1, a socket 4 connected to the energy storage power supply for facilitating plugging of an external plug 3 is fixedly arranged on the energy storage cabinet 2, the energy storage cabinet 2 is provided with an anti-detachment component 5 for automatically fixing the plug 3 after the plug 3 is plugged into the socket 4, the anti-detachment component 5 comprises a guide bin 51 for accommodating the socket 4 therein and a clamping member 52 arranged around the guide bin 51, so as to prevent the plug 3 from being disconnected from the energy storage cabinet 2. A trigger member 53 is arranged inside the guide bin body 51 and can synchronously push all the clamping members 52 inwardly. A first reset connecting member 6 is provided between the clamping member 52 and the guide bin body 51. A second reset connecting member 7 is provided between the trigger member 53 and the guide bin body 51. A trigger driver 8 is also provided on the guide bin body 51 and cooperates with the trigger member 53 to push all the clamping members 52 inwardly. The energy storage cabinet 2 is also provided with a power switch 21 that can control the opening and closing of the energy storage power supply and is electrically connected to the trigger driver 8. When the user turns on the energy storage power supply through the power switch 21, it can be automatically locked or unlocked according to the plug-in and unplugging status between the plug 3 and the socket 4.

[0034] When the user needs to transport the hybrid energy storage power supply to the desired location for use, the user can move it through the universal wheel 11 at the bottom of the mobile frame 1 to ensure that the energy storage power supply can be moved to a suitable position for power supply. When the user determines the position where the energy storage power supply is powered, the user controls the brake pad 111 on the universal wheel 11 to contact the ground, which has a fixing effect on the mobile frame 1, so that it remains at the specified position. When the energy storage power supply in the energy storage cabinet 2 is in the standby state, the clamping member 52 in the anti-detachment component 5 remains in an outwardly opened state under the action of the first reset connector 6, and the trigger member 53 remains in an unactivated state under the action of the second reset connector 7. As the user inserts the plug 3 of the external device that needs to be powered into the socket 4. When the user turns on the energy storage power supply through the power switch 21 on the energy storage cabinet 2. At this time, the start signal of the power switch 21 is simultaneously transmitted to the trigger driver 8, guiding the trigger driver 8 inside the warehouse 51 to activate the trigger member 53, driving the trigger member 53 to push all the clamping members 52 inward. All the clamping parts 52 move inwards under the action of the triggering part 53, thereby tightly restricting the plug 3 to the socket 4. Under the action of the clamping parts 52, the plug 3 is firmly fixed to the socket 4 and will not fall off easily even if subjected to external force. Since the user turns on the energy storage power supply through the power switch 21, the plug 3 and the socket 4 are in a power-on state, and the external device can work normally. When the user stops using electricity and needs to unplug the plug 3 from the socket 4, the user turns off the power supply state of the energy storage power supply through the power switch 21, and the trigger driver 8 releases the driving state of the triggering part 53. Under the action of the first reset connector 6 and the second reset connector 7 of the clamping parts 52 and the triggering part 53, the clamping parts 52 and the triggering part 53 are reset accordingly, and the user can unplug the plug 3 and wait for the next use.

[0035] See also Figure 2-Figure 10 As shown, a slot for the trigger member 53 to slide in is opened on the guide housing 51 along the direction in which the plug 3 is inserted, and a sliding groove for the snap-in member 52 to slide in is opened on the guide housing 51 along the direction perpendicular to the slot. When the trigger member 53 pushes all the snap-in members 52 synchronously, each snap-in member 52 moves toward the center of the guide housing 51, so that the plug 3 is gradually in a fixed state confined between the snap-in member 52 and the socket 4.

[0036] When the user inserts the plug 3 of the external device into the socket 4, the plug 3 is plugged into the socket 4 through the guide housing 51. The user then turns on the energy storage power supply through the power switch 21 on the energy storage cabinet 2, and the turn-on signal of the power switch 21 is transmitted to the trigger driver 8, activating the trigger driver 8. The trigger driver 8 activates the trigger member 53, driving the trigger member 53 to slide along the slot. During the sliding process, the trigger member 53 contacts and pushes the snap-in member 52. Pushed by the trigger member 53, the snap-in member 52 moves along the slide groove and gradually approaches the plug 3. All snap-in members 52 move synchronously, so that the plug 3 is evenly confined between the snap-in member 52 and the socket 4. Even if subjected to external force, it will not fall off easily. After the plug 3 is completely fixed, the user can use the external device normally.

[0037] See also Figure 4-Figure 10 As shown, the clamping member 52 is specifically a block structure, and the triggering member 53 is specifically a ring structure. The edge of the clamping member 52 on one side facing the triggering member 53 has a chamfer 521, and the inner side of the triggering member 53 has an inclined groove 531 that matches the chamfer 521 of the clamping member 52. When the triggering member 53 applies pressure to the clamping member 52 along the chamfer 521 of the clamping member 52 through the inclined groove 531, the clamping member 52 is in a moving state gradually approaching the center of the guide bin body 51.

[0038] When the trigger member 53 slides, the inner inclined groove 531 gradually approaches the chamfer 521 of the clip 52. When the inclined groove 531 of the trigger member 53 contacts the chamfer 521 of the clip 52, the inclined groove 531 and the chamfer 521 begin to contact and gradually fit together. The cooperation between the inclined groove 531 and the chamfer 521 enables the trigger member 53 to apply a gradually increasing pressure to the clip 52 along the chamfer 521 during the sliding process. Under the continuous push of the trigger member 53, the clip 52 gradually moves toward the center of the guide chamber 51 along the slide groove. All the clips 52 move synchronously, and since the plug 3 has an edge protruding outward, it is ensured that the edge of the plug 3 is evenly confined between the clip 52 and the socket 4.

[0039] See also Figure 5-Figure 10 As shown, a rubber pad 522 that can adapt to the edge of the plug 3 is fixedly disposed on the surface of the clamping member 52 that contacts the plug 3 . When the rubber pad 522 contacts the edge of the plug 3 , the rubber pad 522 is in a pressure state that presses the plug 3 toward the socket 4 .

[0040] As the clamping member 52 gradually moves toward the center of the guide housing 51, the rubber pad 522 on the surface of the clamping member 52 gradually approaches the edge of the plug 3. When the rubber pad 522 contacts the edge of the plug 3, due to the elastic characteristics of the rubber pad 522, it will naturally fit the edge of the plug 3 to form a tight contact surface. The adaptability of the rubber pad 522 can adapt to the edges of the plug 3 of different shapes and sizes to ensure a good fit effect. Under the continuous push of the trigger 53, the clamping member 52 continues to move toward the center of the guide housing 51, and the rubber pad 522 is further compressed. The compression of the rubber pad 522 produces a pressure state on the edge of the plug 3 toward the direction of the socket 4. The pressure state not only increases the tightness between the plug 3 and the socket 4, but also improves the fixing stability of the plug 3. The synchronous movement of all clamping members 52 ensures that the plug 3 is evenly confined between the clamping member 52 and the socket 4. Even if it is subjected to external force, it will not fall off easily.

[0041] See also Figure 5-Figure 10 As shown, the guide chamber body 51 is composed of an inner ring 511 and an outer ring 512, and a plurality of balls 532 are provided between the inner side of the trigger member 53 and the inner ring 511 and between the outer side and the outer ring 512 in the circumferential direction around the outer ring 512. The trigger member 53 is provided with a groove for the balls 532 to be embedded therein, and the inner ring 511 and the outer ring 512 are provided with guide grooves 5121 along their axial directions for rolling contact with the balls 532.

[0042] During the sliding process of the trigger member 53, the ball 532 embedded in the groove of the trigger member 53 begins to roll. The ball 532 rolls in the guide groove 5121 of the inner ring 511 and the outer ring 512, reducing the friction between the trigger member 53 and the inner ring 511 and the outer ring 512. At the same time, due to the direction restriction of the guide groove 5121, the trigger member 53 can only move linearly and cannot rotate, avoiding affecting the trigger member 53 from pushing the clamping member 52. With the help of the ball 532, the trigger member 53 slides smoothly along the slot. Due to the reduction of friction, the driving force required for the trigger member 53 when sliding is also reduced accordingly, improving the efficiency and stability of sliding.

[0043] See also Figure 5-Figure 10 As shown, the outer ring 512 has a retaining edge 5122 for limiting the movement range of the trigger member 53. When the end of the trigger member 53 contacts the retaining edge 5122, the clamping member 52 and the trigger member 53 are in a completely staggered state. At this time, the plug 3 is firmly pressed against the socket 4 by the clamping member 52.

[0044] In the initial state, the trigger 53 is located at the starting position of the slot and is not subjected to any external force. When the trigger 53 begins to slide along the slot, as the trigger 53 continues to slide forward, it gradually approaches the rib 5122 on the outer ring 512. The rib 5122 ensures that the trigger 53 can stop when it reaches the maximum stroke. When the trigger 53 continues to slide and finally contacts the rib 5122, its end will first touch the rib 5122. The trigger 53 will be subject to resistance from the rib 5122, preventing it from moving forward. Once the end of the trigger 53 is completely in contact with the rib 5122, the trigger 53 will no longer be able to move forward. In this state, the relative position between the trigger 53 and the clip 52 also reaches a completely staggered state. It is ensured that the clip 52 can correctly contact the plug 3 and exert sufficient pressure on the edge of the plug 3, so that the plug 3 is firmly fixed on the socket 4. When the trigger 53 stops moving, its pressure on the clip 52 reaches the maximum value. Since the trigger member 53 has been in contact with the retaining edge 5122 and no longer moves, the clamping force of the clamping member 52 on the plug 3 remains constant. The edge of the plug 3 is restricted between the clamping member 52 and the socket 4, forming a firm connection.

[0045] See also Figure 5-Figure 10 As shown, the first reset connector 6 and the second reset connector 7 are both tension springs. When the trigger member 53 pushes the clamping member 52 , the first reset connector 6 and the second reset connector 7 are both in a stretched state.

[0046] When the trigger member 53 is not activated, the first reset connector 6 and the second reset connector 7 are both in a natural state, that is, the original length when no external force is applied. When the trigger driver 8 is activated, it starts to apply a thrust to the trigger member 53, pushing the trigger member 53 to slide along the slot. Due to the movement of the trigger member 53, the first reset connector 6 connected thereto begins to be subjected to the tensile force and gradually elongates from its natural state. As the trigger member 53 continues to slide forward, it gradually contacts and pushes the clamping member 52. Under the push of the trigger member 53, the clamping member 52 begins to move along the slide toward the plug 3. At this time, the second reset connector 7 connected to the clamping member 52 also begins to be subjected to the tensile force and gradually elongates from its natural state. When the end of the trigger member 53 contacts the retaining edge 5122, the trigger member 53 stops moving. At this time, the clamping member 52 has completely pressed against the plug 3 and is in a stable position. At this time, the first reset connector 6 and the second reset connector 7 are both in the maximum tension state. When the energy storage power supply is turned off, the trigger driver 8 is turned off accordingly. At this time, under the action of the first reset connector 6 and the second reset connector 7, the trigger member 53 and the clamping member 52 are pulled back to the initial position, releasing the fixing state of the plug 3, making it convenient for the user to pull the plug 3 out of the socket 4.

[0047] See also Figure 5-Figure 10As shown, the trigger member 53 is provided with an avoidance groove for avoiding the second reset connector 7 during the process of pushing the clamping member 52 .

[0048] The avoidance groove on the trigger member 53 effectively avoids the trigger member 53 from interfering with the second reset connector 7 during the process of pushing the clamping member 52, ensuring smoother movement between the trigger member 53 and the clamping member 52, reducing unnecessary friction and wear, and avoiding collision between the trigger member 53 and the second reset connector 7, thereby affecting the fixing of the clamping member 52 to the plug 3.

[0049] See also Figure 5-Figure 10 As shown, the trigger driver 8 has a fixed magnet 81 and a movable magnet 82, the fixed magnet 81 is fixedly connected to the guide bin body 51, and the movable magnet 82 is fixedly connected to the trigger member 53, and the fixed magnet 81 and the movable magnet 82 are both electromagnets. When the trigger driver 8 is not powered on, the movable magnet 82 is located at a position in the guide bin body 51 where it contacts the fixed magnet 81.

[0050] When the trigger driver 8 is not powered, the fixed magnet 81 and the movable magnet 82 are both in a natural state. At this time, the movable magnet 82 contacts the fixed magnet 81 and remains in the initial position. When the trigger driver 8 is powered, the current passes through the fixed magnet 81 and the movable magnet 82, turning the two into electromagnets. When the trigger member 53 is pushed, a repulsive force is generated between the fixed magnet 81 and the movable magnet 82 by changing the direction or magnitude of the current. The movable magnet 82 is acted upon by the repulsive force and pushes the trigger member 53 to move. As the trigger member 53 moves, the first reset connector 6 connected thereto begins to be acted upon by a tensile force and gradually elongates from its natural state. The trigger member 53 continues to slide and push the clamping member 52, and the second reset connector 7 connected to the clamping member 52 also begins to be acted upon by a tensile force and gradually elongates from its natural state. Until the trigger member 53 stops after contacting the retaining edge 5122, during the process of starting the energy storage power supply, the fixed magnet 81 and the movable magnet 82 remain powered, thereby maintaining the limit state of the clamping member 52 to the plug 3. When the energy storage power source is turned off, the fixed magnet 81 and the movable magnet 82 are de-energized, and the trigger member 53 and the clamping member 52 are pulled back to the initial position under the action of the first reset connector 6 and the second reset connector 7. The movable magnet 82 contacts the fixed magnet 81 again and returns to the initial position.

[0051] See also Figure 1 and Figure 2As shown, support components are provided on all four sides of the mobile frame 1 for keeping the mobile frame 1 stable when the energy storage power source is not moved, and the support components include a support rod 12 and a guide cylinder 13 which is sleeved on the support rod 12 and fixed to the mobile frame 1, and a downward drive 14 for driving all the support rods 12 to move vertically downward, and the lower end of the support rod 12 has an anti-slip portion 121 which maintains friction with the ground.

[0052] The downward drive 14 has a lifting plate 141 fixedly connected to all the support rods 12, and an electric push rod 142 fixed on the mobile frame 1 to drive the lifting plate 141 to move. After the user stabilizes the position of the mobile frame 1 by controlling the brake pads 111 of the universal wheel 11 to contact the ground, in order to ensure that the mobile frame 1 is more stable in a non-moving state, the downward drive 14 is started to apply a downward thrust to all the support rods 12. The support rod 12 moves downward along the guide cylinder 13 until the anti-skid portion 121 at its lower end contacts the ground. After the anti-skid portion 121 at the lower end of the support rod 12 contacts the ground, sufficient friction is generated to maintain stable contact with the ground. When all the support rods 12 contact the ground and remain stable, the mobile frame 1 is firmly supported on the ground, and the entire mobile frame 1 is effectively supported without accidental movement or tilting, thereby improving the stability of the energy storage power supply.

[0053] The present invention automatically activates the trigger driver 8 when the energy storage power supply is turned on through the linkage between the trigger member 53 and the clamping member 52, thereby driving the trigger member 53 to push the clamping member 52, so that the edge of the plug 3 is restricted between the clamping member 52 and the socket 4, avoiding the risk of power failure caused by the loosening or falling off of the plug 3. In addition, the rubber pad 522 on the surface of the clamping member 52 can adapt to plugs 3 of different shapes and sizes and apply uniform pressure thereto, further enhancing the tightness and fixing stability between the plug 3 and the socket 4, ensuring the safety and reliability of the connection. When the energy storage power supply is turned off, the clamping member 52 and the trigger member 53 are automatically reset under the action of the first reset connector 6 and the second reset connector 7. At this time, the plug 3 is released from the restricted state, which is convenient for the user to unplug the plug 3, avoiding the trouble and safety hazards of manual unlocking, and improving the user experience.

[0054] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
