[0026] Closing point travel control steps: control the carrier to move inward, close the warehouse door in linkage, and seal the warehouse passage;

[0027] Placement point travel control: Control the carrier to open the door, sense the mobile power supply to be placed in the warehouse for a predetermined distance and control the carrier to move backward until the carrier reaches the closing point and stops, then control the carrier to close the door;

[0028] Timeout control: When the mobile power supply stops temporarily in the warehouse for a preset time and is not taken away, the carrier is controlled to move inwards, drag the mobile power supply back into the warehouse, and the warehouse door is closed to seal the warehouse.

[0029] Furthermore, in the opening point stroke control step: the carrier is controlled to carry the mobile power source out of the warehouse passage, the carrier is linked to release the locking arm and release the restriction on the mobile power source, and the carrier is linked to open the warehouse door to provide the mobile power source.

In this towing mode, not only can the mobile power supply move forward and backward in the inherent warehouse, but the carrier used to clamp the mobile power supply can also move forward and backward in the inherent warehouse. The module can adopt a single power source design, such as a motor to drive the carrier to move, and at the same time link the sliding door to rise and fall, and at the same time link the locking arm to lock or unlock the mobile power supply.

[0046] The module uses three sensors, one for judging when the carrier has reached the opening point, one for judging when the mobile power supply is returned to the warehouse, and one for judging when the carrier has reached the closing point.

[0047] The display light of the module is arranged on the front of the sliding door and can move along with the rising or falling of the sliding door.

It can be a cross structure and is provided on the lower plate 60. The motor 8 is installed in the support structure 66 and covered by the motor cover 83. Of course, the motor 8 can also be installed in other suitable positions of the warehouse body 6. The present invention uses a single power source to simultaneously realize the actions of carrying the mobile power supply, opening and closing the warehouse door, and locking the mobile power supply. The power source usually used is a motor, and other applicable power sources and replacement forms that can be realized by those skilled in the art also belong to the protection scope of the present invention.

[0079] The driving device 80 also includes a transmission device, which transmits the output of the power source such as the motor 8 to the moving carrier to drive the carrier to reciprocate. The transmission device includes but is not limited to a screw nut transmission, a gear meshing, a pulley and other transmission methods to provide power. In the embodiment of the present invention, the screw nut 87 is used as the transmission device.

[0080] In the specific embodiment, the output shaft of the motor 8 is connected to the screw 87, driving the screw 87 to rotate, and the screw 87 is connected to and drives the carrier 3 to reciprocate. A threaded hole (not shown) is provided on the carrier 3, and the screw 87 passes through the threaded hole of the carrier 3, and the two are threadedly matched, so that the carrier 3 is driven to reciprocate along the length direction of the screw 87 through the rotation of the screw.

[0081] As an embodiment, the module 100 adopts a single-motor solution, and the power for the movement of the carrier 3, the sliding door 5, and the locking arm 1 in the module all comes from the DC motor 8. The sliding door 5, the locking arm 1 and the carrier 3 are linked to achieve synchronization in travel.

[0082] The driving device 80 further includes a plurality of sensors. In the specific embodiment of the present invention, the sensor is a micro switch 86. It is understood that other sensors in the prior art are also applicable to sense the position of the carrier and start the power source accordingly. In this embodiment, the module 100 uses three micro switches (sensors) 86, one for judging when the carrier runs to the opening point, and one for judging when the carrier runs to the opening point. Figure 5 and Figure 8 ), a micro switch 860 for determining the insertion point when the mobile power supply is returned to the warehouse ( Figure 5 and Figure 7 ), a closing point micro switch 862 (for judging when the carrier runs to the closing point Figure 5 and Figure 6 ).

[0083] Module 100 adopts a three-micro switch solution. These three micro switches 86 are installed on the lower plate 60 and arranged in accordance with different travels of the carrier for travel control: when the user needs to lend out the mobile power supply, the motor drives the screw 87, which pushes the carrier 3, and the carrier drags the mobile power supply 9 forward until the mobile power supply 9 extends out of the door 5 for a certain distance. At this time, the carrier 3 touches the opening point micro switch 861 and stops. The sliding door 5 is first quickly reset and opened by the tension spring 4. At this time, the locking arm 1 is first quickly reset and raised by the tension spring 4, and the user can take away the mobile power supply. When the mobile power supply is borrowed, the motor 8 rotates in the opposite direction, and the screw 87 pushes the carrier 3 to run backward until the carrier touches the closing point micro switch 862 and stops (compare Figure 6 ), at this time, the sliding door 5 is in a lowered closed state under the pulling force of the connecting rod 2 and the crank 55, and the locking arm 1 is in a downward locked state under the pulling force of the connecting rod 2. When the user returns the mobile power supply or the maintenance personnel replenish the mobile power supply, the motor 8 drives the screw 87, and the screw 87 pushes the carrier 3 to move forward, and the carrier stops until it touches the opening point micro switch 861 (refer to Figure 8 ), the sliding door 5 is first quickly reset and opened under the action of the tension spring 4, at this time, the locking arm 1 is first quickly reset and raised under the action of the tension spring 4, the user or the operation and maintenance personnel can put the mobile power supply into the warehouse for a distance, the carrier 3 clamps the mobile power supply, and the end of the mobile power supply touches the insertion point micro switch 860 at the same time (compare Figure 7 ), at this time, the motor rotates in the opposite direction, and the lead screw 87 pushes the carrier 3 to move backward until the carrier touches the micro switch closing point 862 and stops. At this time, the sliding door 5 is in a lowered closed state under the pulling force of the connecting rod 2 and the crank 55. At this time, the locking arm 1 is in a downward swing under the pulling force of the connecting rod 2 to lock the end of the mobile power supply and is in a charging position.

[0084] As an example, the opening point micro switch 861 is located on the lower plate 60 near the front end or the door, the insertion point micro switch 860 is located behind the opening point micro switch 861, and the closing point micro switch 862 is arranged on the lower plate 60 near the rear end of the bin body. When the carrier moves to different strokes, its bottom 301 touches the micro switch at the corresponding position to start the motor 8 accordingly. Of course, the micro switch can also be arranged at other suitable positions.

[0085] The main control 70 can be implemented by a PCB board or a chip. The main control 70 of this embodiment adopts a main control PCB board, and the charging needle seat 7 is arranged on the main control PCB board. The main control PCB board is installed on the corresponding side wall of the warehouse body (such as the rear wall). The charging needle seat 7 passes through the charging needle seat opening arranged on the side wall of the warehouse body and elastically extends toward the mobile power supply. The motor 8 is controlled by the main control 70.

[0086] In a specific embodiment, the main control PCB board 70 is installed at the rear end of the compartment body 6, and its charging pin socket 7 can provide charging and communication for the mobile power supply.

[0087] The speed of the motor 8 used in the module 100 can also be designed to be variable speed according to the program requirements, and the speed of the motor 8 is adjusted by the DC speed regulator of the main control PCB board 70, which can shorten the waiting time of the user when returning the mobile power supply or lending the mobile power supply. The module 100 uses a DC motor 8, and the DC speed regulator of the main control PCB board 70 adjusts the speed of the motor. Before the user returns the mobile power supply, there is no mobile power supply in the module warehouse, and the load of the carrier is relatively light. In this case, the main control PCB board 70 increases the speed of the motor 8 through the DC speed regulator, allowing the carrier 3 to quickly reach the position of the micro switch 861 at the opening point and quickly open the warehouse door 5 and the locking arm 1 accordingly, shortening the user's waiting time. When the user takes out the mobile power supply, there is no mobile power supply in the module warehouse, and the load of the carrier 3 is also relatively light. In this case, the main control PCB board 70 increases the speed of the motor through the DC speed regulator, allowing the carrier to quickly return to the position of the micro switch 862 at the closing point and quickly close the warehouse door 5 and the locking arm 1 accordingly, shortening the user's waiting time. When there is a mobile power source in the warehouse, in order to maintain sufficient torque to drag the mobile power source into or out of the warehouse 63, the motor 8 needs to be restored to normal speed or adjusted to low speed, so that the motor output torque is large, and the driving force provided to the carrier 3 is sufficient to overcome the friction and spring force of the mobile power source 9 during movement.

[0088] The mobile power charging module 100 of the embodiment of the present invention has strong compatibility with the towing capacity of different types of mobile power supplies by means of the structure of the mobile power supply entering and exiting the warehouse channel and the sensor judgment setting. It can be installed horizontally or vertically in the mobile power supply device 1000 for use, and the cost of the module 100 is also reduced. The module 100 drives the movable carrier 3 to clamp the mobile power supply 9 to tow out of the warehouse channel 63 and tow into the warehouse channel 63 through a single motor 8. In this towing mode, not only the mobile power supply 9 can move forward and backward in the inherent warehouse channel 63, but also the carrier 3 used to clamp the mobile power supply can be movable in the inherent warehouse channel 63 and can move forward and backward. Preferably, the module 100 adopts a single motor 8, which is used to drive the screw 87 to rotate and push the carrier 3 to move, and at the same time link the sliding door 5 to rise and fall, and at the same time link the locking arm 1 to lock or unlock the mobile power supply.

[0089] The mobile power charging module 100 is installed on the charging rental equipment 1000 for use. The working principle of the charging module 100 is: the main control 70, for example, the main control PCB board 70 controls the DC motor 8 to drive the screw 87 to rotate and push the carrier 3 with the built-in nut structure to drag the mobile power back and forth to move out of the warehouse or into the warehouse. While the carrier 3 moves, the lifting movement of the sliding door 5 is linked to achieve opening or closing, and at the same time, the swing movement of the locking arm 1 is linked to achieve unlocking or locking.

[0090] When the user rents a mobile power bank, the carrier 3 carries the mobile power bank 9 out of the warehouse passage 63, the carrier 3 releases the locking arm 1 and releases the restriction on the mobile power bank 9, and the carrier 3 opens the sliding door 5 to borrow the mobile power bank 9. If the mobile power bank 9 is taken away, the carrier 3 moves inward, tightens the locking arm 1 in an empty warehouse locking state, and closes the sliding door 5, closing the warehouse passage 63 to protect the electrical safety and dust in the warehouse passage 63. If the mobile power bank 9 is not taken away and temporarily stops in the warehouse passage 63, after a preset time, the carrier 3 moves inward, drags the mobile power bank back into the warehouse passage 63, tightens the locking arm 1 in a locking state, locks the mobile power bank 9 in a charging position, and closes the sliding door 5 in a locking state to close the warehouse passage 63 to protect the electrical safety and dust in the warehouse passage.

[0091] When the user returns the mobile power supply, the carrier 3 moves outward, which in turn opens the locking arm 1 and the sliding door 5. The user puts the mobile power supply into the warehouse passage 63 and touches the micro switch 86. Then the carrier 3 carries and clamps the mobile power supply 9 back into the warehouse passage and returns it to its position for charging. The carrier 3 in turn tightens the locking arm 1 and locks the mobile power supply. The carrier in turn closes the sliding door 5 and seals the warehouse passage 63 to protect the electrical safety and dustproofing of the warehouse passage.

[0092] The module 100 is further provided with a lighting device, including a display light bar 52 provided on the front of the sliding door, which can move with the sliding door 5 as it rises or falls. Therefore, it can provide a display indication to the user when renting and returning the mobile power supply 9. The lighting device can also be further provided with a display spotlight 53.

[0093] The assembly and functions of the various components of the module are as follows.

[0094] The front side wall of the warehouse body 6 is provided with a slide groove 69 for installing the sliding door 5. The sliding door can slide up and down in the slide groove 69. When the sliding door 5 rises, the warehouse door can be opened, and when the sliding door falls, the warehouse door can be closed. A display light bar 52 is installed on the front of the sliding door, which can rise or fall with the sliding door. The display light bar 52 provides a warehouse path prompt for users when renting and returning the mobile power supply.

[0095] The motor 8 is installed at the front of the bin body 6, and the motor is fixed by a motor cover 83. The motor shaft end can be connected to one end of a screw rod 87. The middle end of the screw rod 87 is screwed into the screw hole of the carrier, and the other end of the screw rod rests in the shaft hole of the rear wall of the bin body 6. The motor drives the screw rod 87 to rotate, and the carrier 3 is driven to move forward or backward through the screw nut.

[0096] The carrier 3 is installed in the accommodating cavity of the warehouse body 6, that is, the warehouse passage 63, and can move forward and backward in the accommodating cavity of the warehouse body 6. Clamping blocks 36 are installed inside the two sides of the carrier 3. The clamping blocks 36 are used to clamp the mobile power supply 9, so that the carrier can drag the mobile power supply into the warehouse passage 63 or drag it out of the warehouse passage. There are guide pillars 35 on both sides of the carrier. After being installed in the warehouse body 6, the guide pillars 35 can limit the movement of the carrier 3 in the side slide groove of the warehouse body 6. On the one hand, it can limit the relatively stable movement of the carrier in a small gap, and on the other hand, when the module is inverted, it can prevent the carrier 3 from loosening from the warehouse body 6.

[0097] The crank 55 is mounted on the rotating shaft 65 of the side wall of the bin body, with the front end connected to the sliding door 5 and the rear end connected to the connecting rod 2. A pin connecting the tension spring 4 is provided between the rotating shaft hole and the front end of the crank 55. The tension spring 4 is often in a stretched state, which can provide elastic force for the crank 55 to drive the sliding door to reset and open.

[0098] One end of the connecting rod 2 is connected to the crank 55, and the other end has a boss 27 and is inserted into the horizontal slide groove on the bottom plate 60 of the warehouse body 6. The boss 27 is on the trajectory of the vehicle, so it can be pushed and pulled by the vehicle 3. When the vehicle 3 moves backward, the vehicle pushes and pulls the boss 27 of the connecting rod, and then pulls the crank 55 to swing, and the crank drives the sliding door to move downward, so that the warehouse door is closed. When the vehicle moves forward, the vehicle 3 is away from the boss 27 of the connecting rod, and with the release distance, the connecting rod 2 loses its pulling force on the crank 55. At this time, the tension spring 4 can pull the crank 55 to swing upward, so that the warehouse door is opened.

[0099] One end of the connecting rod 2 is connected to the locking arm 1, and the other end has a boss 27 and is inserted into the hollow chute of the carrier. The boss is on the trajectory of the carrier, so it can be pushed and pulled by the carrier. When the carrier 3 moves backward, the carrier pushes and pulls the boss 27 of the connecting rod, and then pulls the locking arm 1 to swing, so that the locking arm can lock the end of the mobile power supply, lock the mobile power supply in the charging position, and block the locking arm 1 in the warehouse, which can also prevent the risk of the mobile power supply being maliciously taken out. When the carrier moves forward, the carrier is away from the boss 27 of the connecting rod. With the release distance, the connecting rod loses its pulling force on the locking arm. At this time, the tension spring can pull the locking arm to swing upward, so that the locking arm 1 can unlock the end of the mobile power supply. After the locking arm 1 is raised above the mobile power supply, the mobile power supply can enter and exit the warehouse from the bottom of the locking arm.

[0100] The connecting rod 2 driving the locking arm 1 and the connecting rod 2 driving the crank 55 can be the same or two different ones, and can be arranged in the same direction or opposite to each other.

[0101] The other components of the mobile power module 100 are described in detail below.

[0102] Refer again Fig.10 and Figures 16 to 18 The mobile power charging module 100 of the present invention includes a door opening and closing device 50, which is arranged on the warehouse body 6. The opening and closing device is a linkage opening and closing device, and the warehouse door 50 is driven by the linkage device to open and / or close. The door opening and closing device 50 includes a warehouse door 5, and the linkage device includes a linkage connecting rod 2, a crank 55, and an elastic member such as a tension spring 4. The warehouse door 5 is movably installed at the front end of the warehouse body 6, and the crank 55 is movably installed on the warehouse body 6. The crank 55 is respectively connected to the linkage connecting rod 2 and the elastic member such as the tension spring 4, and the linkage connecting rod 2 and the elastic member tension spring 4 cooperate with each other to drive the crank 55 to move. The warehouse door 5 is connected to one end of the crank 55, and is driven by the crank 55 to move together to open or close the warehouse entrance.

[0103] The mobile power charging module 100 can carry the mobile power 9 in and out of the warehouse passage 63 and charge the mobile power 9. While carrying the mobile power 9, the linkage door opening and closing is performed through the connecting rod 2, that is, when there is a mobile power 9 or not in the warehouse passage 63, the door 5 can be in a normally closed state, which is also suitable for protecting the mobile power 9 with charging terminals at both ends, and provides closed protection for the mobile power module 100 and the mobile power 9. The mobile power in and out of the warehouse passage 63 drives the door to open or close through the linkage device, and specifically, the mobile power in and out activity is performed and completed by the reciprocating motion of the carrier 3.

[0104] The door 5 is located at the front end of the mobile power charging module 100, and the door 5 is movably matched with the front ends of the left and right side walls of the warehouse body to close or open the entrance and / or exit of the mobile power.

[0105] In this embodiment, the door 5 is configured as a sliding door, which can be installed at the front end of the warehouse body 6 to slide up and down to open or close the warehouse entrance. For example, the door 5 is opened when sliding up, and is closed when falling down. The door 5 is slidably matched with the front ends of the left and right side walls of the warehouse body. The sliding match can be a sliding match between a sliding support and a slide groove. The sliding support includes a slide rail, a guide rail, a roller, a slider, a protrusion, a block, a latch, etc. or other sliding support structures, which cooperate with the slide groove and can slide relative to each other. Refer to Fig.10 , the front ends of the left and right side walls of the warehouse body are provided with slide grooves 69, and the two sides of the warehouse door 5 are provided with slide rails 54, and the two sides of the warehouse door 5 are slidably abutted against the front side walls of the warehouse body, and the slide rails 54 are embedded in the slide grooves 69 for sliding cooperation. It can be understood that the sliding rails and slide grooves for sliding cooperation can be arranged in a transposed manner, that is, the slide rails can also be arranged at the front ends of the left and right side walls of the warehouse body 6, and the slide grooves are arranged on the warehouse door 5. At least one mushroom head latch 51 is further arranged on both sides of the warehouse door, and the latch 51 further extends to the corresponding side. The side walls of the warehouse body are provided with through holes 61, and the latch 51 passes through the through holes 61 ( Fig.16) and connected to the crank 55. The shape and configuration of the through hole 61 are consistent with the moving trajectory of the latch 51 along the door 5. In this embodiment, the door 5 slides up and down, so the through hole 61 is a vertical hole set on the side wall, and its length is consistent with the height of the door sliding up and down. When the door 5 slides up and down, the latch 51 set on at least one side thereof also moves up and down.

[0106] Refer again Fig.18 The crank 55 of the embodiment of the present invention includes a front arm 53 and a rear arm 56, and the two end arms are formed into an L shape. The front arm 53 is connected to the warehouse door 5 to drive the warehouse door 5 to slide up or fall down; the rear arm 56 is connected to the linkage connecting rod 2, and the crank 55 is driven by the connecting rod 2 to move. The crank 55 is further movably mounted on the warehouse body 6, and is further elastically fixed to the warehouse body 6 by the elastic member tension spring 4. The crank 55 is driven to move on the warehouse body through the elastic force of the connecting rod 2 and the elastic member tension spring 4, thereby driving the warehouse door 5 to open or close, such as sliding up or falling. The connection between the crank 55 and the warehouse door 5, the connection between the crank 55 and the connecting rod 2, and the connection between the crank 55 and the warehouse body 6 can be achieved by the movable or fixed cooperation between the connecting shaft and the shaft hole or the connecting structure. The position settings of the connecting shaft and the shaft hole are interchangeable. The connection between the crank 55 and the door 5 is through the matching connection between the mushroom head pin 51 as the connecting shaft and the slide slot 551 as the shaft hole. The pin 51 can rotate or move relatively in the slide slot 551 to realize the movement of the crank 55 to drive the door 5 to open or close. The connection between the crank 55 and the connecting rod 2 is through the matching connection between the mushroom head pin 552 as the connecting shaft and the slot 29. The pin 552 can rotate or move relatively in the slot 29, so that the crank 55 is driven by the connecting rod 2. The connection between the crank 55 and the warehouse body 6 is through the matching connection between the rotating shaft 65 as the connecting shaft and the rotating shaft hole 550. The rotating shaft 65 can rotate or move in the rotating shaft hole 550 to support the crank 55 movably. The mushroom head structure is used for limiting, the same below.

[0107] As a setting method, the rotating shaft hole 550 is provided at the corner where the two arms of the crank 55 intersect, or in the middle of the crank 55, the front end arm 53 is provided with an elliptical slide groove 551, the rear end arm is provided with a mushroom head pin structure 552, and a screw hole boss 553 is provided between the elliptical slide groove 551 and the rotating shaft hole 550, that is, preferably, one end of the elastomer is fixed to the front end arm of the crank close to the rotating shaft 65, that is, close to the middle of the crank.

[0108] Correspondingly, a rotating shaft 65 and a screw hole boss are correspondingly arranged on the side wall of the bin body, preferably, arranged at the front end of the outer side wall of the bin body for fixing the other end of the elastic body.

[0109] The shaft hole 550 of the crank 55 is mounted on the shaft 65 of the side wall of the warehouse body (the shaft 65 and the shaft hole 550 are interchangeable), the front end elliptical slide groove 551 is mounted on the mushroom head pin 51 of the sliding warehouse door 5 (the pin 51 and the slide groove 551 are interchangeable), the rear end mushroom head pin 552 is inserted into the slot 29 of the connecting rod 2 (the pin and the slot are interchangeable), one end of the tension spring 4 is fastened to the screw hole boss 553 of the crank 55, and the other end of the tension spring 4 is fastened to the screw hole boss (not shown in the figure) on the side wall, and the two ends of the tension spring are clamped by screws.

[0110] In this embodiment, the connecting rod 2 is a straight rod structure, including a front end 25 and a rear end 26. The front end 25 is provided with a slot 29, and the rear end 26 is convexly provided with a locking pin 27 or other locking structure. The slot 29 of the connecting rod 2 is sleeved on the mushroom head pin 552 of the crank 55. The linkage connecting rod 2 is placed in the warehouse channel 63 along the direction of the mobile power supply entering and exiting. Preferably, the connecting rod 2 is placed in the slide groove 302, 302' on the side wall of the warehouse body for the carrier 3 to slide, and the locking pin 27 is stuck in the slide groove of the side wall of the warehouse body and protrudes laterally. The locking pin 27 on the rear end 26 of the connecting rod 2 can be pushed and moved by the reciprocating carrier 3 or the mobile power supply 9, thereby driving the crank 55 to move, and further driving the warehouse door 5 to open and close in a linkage manner. The carrier 3 and the connecting rod 2 cooperate with each other in a locking linkage or a releasing linkage. In the locking linkage, when the carrier 3 moves backward, it pushes the locking structure on the connecting rod, synchronously pushing the connecting rod 2 to move, thereby driving the warehouse door 5 connected to the crank 55 to move downward and close.

[0111] The carrier 3 is driven by the screw 87 to move straight back and forth in the warehouse channel 63. Its structure can be set on the support structure at the top and / or bottom of the warehouse channel, and can move back and forth. In this embodiment, the carrier is supported on the warehouse body so that it can move back and forth. A clamping block 36 for clamping the mobile power supply 9 is provided on the carrier 3 to carry the mobile power supply 9 in and out of the warehouse channel 63. The carrier 3 and the warehouse body are connected by a sliding fitting structure, for example, a guide column 35 (such as a guide column 35) is provided on the side wall of the carrier. Fig.11 ), and is inserted into the slide groove on the side wall of the bin body 6 for sliding cooperation, so that the carrier 3 is slidably supported on the bin body 6, and the end of the carrier 3 is a pushing end face 31. The linkage connecting rod 2 is inserted into the carrier 3, and the positioning pin 27 on the rear end 26 of the connecting rod 2 can be clamped on the pushing end face 31 of the carrier, and is pushed and pulled by the carrier 3 to the rear of the bin body, thereby driving the connecting rod 2 to be pulled backward.

[0112] The sliding door 5 is opened and the mobile power supply 9 is rented:

[0113] When the user rents the mobile power supply 9, the carrier 3 carries the mobile power supply 9 straight toward the warehouse door 5. The pushing force of the end surface 31 of the carrier 3 on the connecting rod 2 is gradually reduced and space is released. The crank 55 connected to the connecting rod 2 rotates a certain angle and resets upward under the elastic force of the tension spring 4, pushing the sliding warehouse door 5 to rise and open. The carrier can then transport the mobile power supply 9 from under the sliding warehouse door 5 out of the warehouse passage 63 for the user to take the mobile power supply away.

[0114] Then, after the mobile power source 9 is taken away, the carrier 3 moves straight into the warehouse channel until the carrier push end surface 31 begins to gradually apply a pushing force to the connecting rod 2 while pulling the connecting rod 2 to move backward, and the connecting rod 2 pulls the crank 55 to rotate a certain angle and swing downward, and the crank 55 pushes the sliding warehouse door to drop and close.

[0115] The process of opening the sliding compartment 5 and returning the mobile power supply 9:

[0116] When the user returns the mobile power supply 9, the carrier 3 moves straight toward the warehouse door 5, and the pushing force of the carrier pushing end surface 31 on the connecting rod gradually decreases while releasing space. The crank 55 connected to the connecting rod 2 rotates a certain angle and resets upward under the elastic force of the tension spring, pushing the gradually sliding warehouse door 5 to rise and open. At this time, the warehouse opening below the warehouse door can be used for the user to return the mobile power supply and put it on the carrier 3 in the warehouse channel 63.

[0117] Then, when the mobile power source 9 is placed on the carrier 3, the carrier 3 carries the mobile power source 9 straight into the warehouse, and the carrier pushes the end surface 31 to gradually apply a pushing force to the connecting rod while pulling the connecting rod to move backward, and the connecting rod 2 pulls the crank 55 to rotate a certain angle and swing downward, and the crank 55 pushes the sliding warehouse door 5 to gradually descend and close.

[0118] The above-mentioned reciprocating motion of the carrier 3 is driven by the motor 8, which can simultaneously carry out the reciprocating motion of the mobile power supply and the linkage motion of the sliding door 5. The mobile power charging module 100 can carry out the in-and-out warehouse passage 63 of the mobile power supply 9 and charge the mobile power supply 9. While carrying the mobile power supply 9, the linkage sliding door opening and closing is performed through the connecting rod 2, that is, when there is a mobile power supply in the warehouse passage or when there is no mobile power supply, the sliding door 5 can be in a normally closed state, which provides closed protection for the mobile power supply module and the mobile power supply. The above-mentioned door opening and closing structure 50 of the present invention can realize that the mobile power charging module only uses one motor 8, and can simultaneously carry out the reciprocating motion of the mobile power supply 9 and the linkage motion of the sliding door 5. The single motor 8 can reduce the cost of electronic components of the module and simplify the structure.

[0119] Reference Figure 5-8Furthermore, a locking device 10 is also provided in the mobile power charging module 100 of the present invention to lock or unlock the end of the mobile power, so that the mobile power can be locked when charging in the warehouse passage and can be unlocked when sent out of the warehouse passage 63.

[0120] The reciprocating movement of the carrier 3 of the mobile power charging module 100 of the present invention can also drive the locking device 10 to lock or unlock the end of the mobile power. The locking device 10 of the mobile power is arranged in the warehouse body 6, at the front end of the warehouse channel, and can lock or unlock the mobile power in the warehouse channel. As an embodiment, the locking device 10 is installed on the support structure 66 on the lower plate 60.

[0121] Combined with reference Figures 19-20 The locking device 10 includes a locking arm 1, another connecting rod 2 and another tension spring 4. The locking arm 1 is installed on the support structure 66 at the front end of the warehouse channel. As an embodiment, the support structure 66 is erected above the locking arm 1, and the locking arm 1 and the support structure 66 are rotatably matched. One end of the tension spring 4 is installed on the locking arm 1, and the other end is installed on the support structure 66, so that it elastically expands and contracts between the locking arm 1 and the support structure 66 to pull the locking arm to swing up and down or rotate. One end of the connecting rod 2 is movably installed on the locking arm 1 and can pull the locking arm to swing in the opposite direction to the rebound force of the tension spring, and lock the mobile power supply, for example, swing downward to press against the end of the mobile power supply. When the connecting rod 2 is not pulled backward or pushed, the rebound force of the tension spring 4 pulls the locking arm 1 upward until it is unlocked.

[0122] The locking arm 1 includes a locking end surface 11, which can tighten the end of the mobile power supply to keep the mobile power supply in the charging position. As an embodiment, the locking end surface 11 can form a clamping fit with the end of the mobile power supply. In a more specific example, the locking end surface is a vertical stop arm extending from the lower end of the locking arm, such as Fig.19 When the locking arm 1 is pulled down to a vertical position by the connecting rod 2, the locking end surface 11 is pressed against the end of the mobile power supply, and the entire mobile power supply is clamped between the rear wall of the compartment body and the locking arm 1. The charging terminal of the mobile power supply is pressed against the charging pin seat on the rear wall of the charging module, and charging can be performed.

[0123] The locking arm 1 is provided with a screw through hole 12 for mounting a tension spring hook, and the tension spring hook can be hung with a screw. As a specific embodiment, a pair of through holes 12 are correspondingly provided on a pair of left and right limiting side surfaces 15 of the locking arm 1, and a screw or a fixed shaft passes through the pair of through holes 12 and is fixed, and the screw or the fixed shaft hangs and fixes the hook at one end of the tension spring 4, and fixes one end of the tension spring 4 between the pair of limiting side surfaces 15, preferably in the middle position.

[0124] The locking arm is provided with a rotating shaft 13, and a beak 67 is correspondingly provided on the front end support structure 66 of the warehouse channel, and a rotating shaft hole 670 is provided on the beak 67. The rotating shaft 13 of the locking arm is rotatably installed in the beak rotating shaft hole 670 of the support structure 66, and the rotation of the rotating shaft 13 drives the locking arm 1 to swing around this rotating shaft 13. The rotating shaft 13 is connected and fixed between the two limiting surfaces 15 and is located at the upper end of the locking arm 1. The beak 67 installed on the support structure 66 is located between the two limiting surfaces 15, and the rotating shaft 13 is penetrated in the beak rotating shaft hole 670 of the support structure. The rotating shaft 13 of the locking arm 1 is stuck in the beak rotating shaft hole of the support structure 66 and can swing around this rotating shaft hole. In this embodiment, the beak rotating shaft hole 670 is a hole with an open top, forming a rotation support for the rotating shaft 13.

[0125] The locking arm 1 includes left and right limiting side surfaces 15, which are parallel limiting surfaces 15 on both sides in this embodiment. The two parallel limiting surfaces 15 are located on both sides of the hawk's beak 67 of the support structure 66. The connecting rod 2 is assembled between the two parallel limiting surfaces 15, so that the locking arm 1 can swing smoothly to a certain extent and limit its large left and right angle shaking. On the other hand, when the locking arm 1 is to be stuck in the hawk's beak shaft hole 670 of the support structure 66, an assembly space is formed between the two parallel limiting surfaces 15 to accommodate the hawk's beak 67 of the support structure 66, which can avoid interference during the swinging process, and the structural coordination is relatively compact.

[0126] The locking arm 1 is provided with a slot 14, specifically, on the limiting surface 15, for connecting the connecting rod 2 to the locking arm 1. The slot 14 is preferably an arcuate slot, which can be tilted, for example, tilted downward from the back to the front.

[0127] In one embodiment, the connecting rod 2 in the locking device 10 has the same or substantially the same structure as the connecting rod 2 used in the door opening and closing device 50 , and the connecting rod 2 is placed consistently along the direction in which the mobile power source enters and exits.

[0128] As an embodiment, the front end 25 of the connecting rod 2 is provided with a pin protruding vertically, and the pin can be installed in the arc groove 14 of the locking arm 1 in a tensioned and movable manner. The protruding pin on the front end 25 of the connecting rod is installed in the slot 14 movably and non-detachably, and is limited by the larger end of the pin being clamped on the outer side of the slot. The pin can be directly formed on the end of the connecting rod 2, for example, integrally formed on the end 25; or a slot hole 29 is provided on the end 25 of the connecting rod 2, and the pin is installed in the slot hole 29. In an embodiment of the present invention, the pin shaft is a mushroom head pin structure 552 arranged on the crank 55 of the warehouse door opening and closing device 50, and mushroom head pin structures 552 are arranged on both sides of the crank 55. The mushroom head pin structure 552 on one side is inserted into the slot 29 of the connecting rod 2 of the opening and closing device 50 for active cooperation, and the mushroom head pin structure 552 on the other side is inserted into the slot 29 of the connecting rod 2 of the locking device. In this way, the connecting rod 2 of the locking device and the opening and closing device are synchronously pushed by the carrier 3, and the locking / unlocking and warehouse door opening and closing activities are synchronously performed.

[0129] The locking pin 27 formed on the rear end 26 of the connecting rod 2 is clamped on the pushing end face 31 of the carrier, and is pushed and pulled by the carrier 3 toward the rear of the warehouse body, thereby driving the connecting rod 2 to be pulled backward, and the upper end of the locking arm 1 swings downward around the rotating shaft 13 in the eagle-shaped rotating shaft hole of the supporting structure and the lower end around the pin in the arc-shaped groove 14. When the connecting rod 2 is not subjected to the pushing force, the resilience of the tension spring 4 pulls the locking arm 1 upward, and at this time, the upper end of the locking arm 1 swings upward around the rotating shaft 13 in the eagle-shaped rotating shaft hole of the supporting structure and the lower end around the pin in the arc-shaped groove 14.

[0130] The pin on the front end 25 of the connecting rod 2 is inserted into the arc groove 14 provided on the limiting surface, and the locking pin 27 on the rear end 26 can be pressed against by the carrier 3 and pushed backward.

[0131] It is understood that the locking pin 27 of the connecting rod rear end 26 can also be locked on the end surface of the mobile power supply, so that the mobile power supply entering is pushed backward. The locking pin 27 can also be assembled into one by setting a mounting hole on the rear end 26, or a structure formed integrally with the connecting rod.

[0132] In this embodiment, the connecting rod 2 is a straight rod inserted into the carrier 3. More specifically, the connecting rod 2 is located on the left and / or right side of the bottom wall of the warehouse channel 63, passes through the carrier 3, and the rear end 26 is pushed by the carrier 3.

[0133] In one embodiment, the rotating shaft 13 of the locking arm 1 is located at the top, the screw through hole 12 is located at the front end at the bottom, and the arc groove 14 is located at the rear end at the bottom. In short, the position and shape configuration of the through hole 12, the locking end surface 11, the rotating shaft 13, the arc groove 14 and the limiting surface 15 of the locking arm 1 meet the requirements of the overall locking device structure balance, stable swing of the locking arm 1, and smooth locking and unlocking.

[0134] The support structure 66 is vertically arranged at the front end of the warehouse channel 63, above the entrance of the mobile power supply. The beak 67 arranged on the support structure 66 extends backwards into between the two parallel limiting surfaces 15 of the locking arm 1, and the top forms a beak shaft hole 670 to rotatably support the shaft 13 of the locking arm 1. The support structure 66 extends forward to form a screw hole 68 for installing the other end of the tension spring 4, and the other end of the tension spring is fixed by a screw, and is located above the screw through hole 12 of the locking arm.

[0135] One end of the tension spring 4 is connected to the screw through hole 12 of the locking arm, and the other end is connected to the screw hole 68 of the supporting structure 66. The tension spring expands and contracts accordingly as the locking arm 1 swings.

[0136] The front end 25 of the connecting rod 2 is connected to the arc groove 14 of the locking arm 1. The connecting rod 2 can tighten or relax the locking arm 1 through the arc groove 14, and can apply a tightening force on the end of the mobile power supply. The other end 26 of the connecting rod 2 is provided with a locking pin 27 which can be pushed and pulled by the carrier 3. When the carrier 3 moves inward, it can push the connecting rod 2 to move inward accordingly, thereby providing a pulling force for the locking arm 1 to swing.

[0137] In the embodiment of the present invention, the locking arm 1 is located between the warehouse door 5 and the carrier 3. The mobile power charging module 100 relies on the carrier 3 to carry the mobile power 9 in and out of the warehouse passage 63. When the carrier 3 moves back and forth, the linkage connecting rod 2 pulls the locking arm 1 to swing around the rotating shaft 13. When the locking arm 1 swings upward, the unlocking action of the end of the mobile power is performed, and when the locking arm 1 swings downward, the locking action of the end of the mobile power is performed, until the charging terminal of the mobile power is pressed against the charging needle seat spring of the module to retract a certain distance before stopping. When the carrier 3 runs to the position and stops, the connecting rod 2 and the locking arm 1 swing and stop accordingly, and the locking arm 1 still keeps the tension on the end of the mobile power, thereby limiting the space for the mobile power 9 to retreat, so that the mobile power 9 remains in the charging contact position, and the locking force is relatively reliable.

[0138] Lock arm opening and mobile power lending process:

[0139] When the user rents or needs to take out the mobile power supply 9, the carrier 3 carries the mobile power supply 9 straight toward the warehouse door 5, and the pushing force of the end surface 31 of the carrier 3 on the connecting rod 2 is gradually reduced while releasing space. The locking arm 1 connected to the connecting rod 2 rotates a certain angle and resets upward under the elastic force of the tension spring 4. The spring 4 pulls the locking arm 1 to swing around the rotating shaft 13 until the locking arm 1 swings higher than the upper surface of the mobile power supply 9. The locking arm 1 unlocks the mobile power supply 9, and the carrier 3 can continue to carry the mobile power supply 9 out of the warehouse passage 63 for the user to take the mobile power supply away.

[0140] Then, after the mobile power source 9 is taken away, the carrier 3 moves straight into the warehouse channel until the carrier 3 pushes the end surface 31 and begins to gradually apply a pushing force to the locking pin 27 of the connecting rod 2 while pulling the connecting rod 2 to move backward. The connecting rod 2 then pulls the locking arm 1 to swing downward around the rotating axis at a certain angle and is in an empty warehouse locking state. At this time, the tension spring 4 is stretched.

[0141] Lock arm opening and mobile power supply return process:

[0142] When the user returns or puts in the mobile power supply 9, the carrier 3 moves straight toward the warehouse door 5, and the pushing force of the pushing end surface 31 of the carrier on the connecting rod gradually decreases while releasing space. The locking arm 1 connected to the connecting rod 2 swings around the rotating axis at a certain angle under the elastic force of the tension spring 4 to reset, until the locking arm 1 swings higher than the upper surface of the mobile power supply 9, and the mobile power supply 9 can be placed on the carrier 3. The carrier 3 carries the mobile power supply 9 and moves straight toward the warehouse channel. The pushing end surface 31 of the carrier begins to gradually apply a pushing force to the connecting rod 2 and pulls the connecting rod 2 to move backward. The connecting rod 2 pulls the locking arm 1 to rotate a certain angle to just tighten the mobile power supply from the rear end face of the mobile power supply 9, and overcomes the spring force of the module charging needle seat and compresses the spring to a certain amount. When the carrier 3 stops, the connecting rod 2 and the locking arm 1 stop swinging synchronously, so as to lock the mobile power supply 9, and the tension spring 4 is stretched at this time.

[0143] Two locking devices 10 are arranged at the front end of the warehouse channel, which are arranged symmetrically on the left and right. Of course, one or more locking devices can also be arranged.

[0144] The rotational cooperation between the locking arm 1 and the supporting structure 66 may also be achieved by setting the rotating shaft 13 on the supporting structure 66 , and correspondingly, the rotating shaft hole 670 is set on the limiting surface 15 of the locking arm 1 .

[0145] Similarly, the connecting rod 2 and the locking arm 1 can be movably matched, and the protruding pin can also be set on the locking arm 1, while the arc-shaped slot 14 is set on the connecting rod 2.

[0146] As another embodiment, the locking device 10 can also be configured such that the tension spring tensions the locking end surface of the locking arm 1 to lock the mobile power source, while the connecting rod 2 pulls the locking arm to unlock it.

[0147] As a modified embodiment, the tension spring 4 can be replaced by a torsion spring, a spring, a spring sheet or an elastomer, or other elastic member, and the elastic force of the elastic member can be used for reset.

[0148] In other embodiments, the charging terminals of the mobile power supply may be arranged at both ends or at the front or rear end or at other surfaces, and accordingly, the charging pin holder 7 is arranged at a corresponding position of the side wall of the bin body 6. The locking device 10 can be arranged at the front or rear end of the bin or at other suitable positions to lock the end of the mobile power supply.

[0149] In the present invention, only one motor 8 is used to drive the screw 87 to rotate, thereby driving the carrier 3 to reciprocate. The carrier 3 carries the mobile power supply 9 to move in and out of the warehouse channel 63, pulling the connecting rod 2, thereby driving the locking device 10 and the warehouse door opening and closing device 50 to lock / unlock and open and close the warehouse door in a linkage manner. The linkage connecting rod 2 cooperates with the elastic force of the elastic member 4 to complete the locking / unlocking of the mobile power supply and the opening and closing of the warehouse door.

[0150] Reference Figures 10 to 15 The mobile power supply charging module has a clamping device 30 for carrying the mobile power supply 9 in and out of the warehouse passage 63, so that the mobile power supply 9 can be charged or sent out for use. The clamping device 30 is located above the lower plate 60 of the warehouse body 6 and can reciprocate. The lower plate 60 is located at the bottom of the warehouse body 6, and the top surface of the lower plate 60 is provided with two (but not limited to two) support ribs 62, which are used to support the mobile power supply 9 and bear the weight of the mobile power supply 9. The top surface of the lower plate 60 is also provided with two (but not limited to two) rails 64, and the clamping device 30 reciprocates along the rails 64 through the wheels 34 installed at the bottom thereof.

[0151] Reference Figures 10 to 15 The clamping device 30 of the present invention includes a carrier 3 and a clamping block 36, and the clamping block 36 is clamped on the side wall of the carrier to form a clamping structure of the mobile power supply. The two clamping blocks 36 are respectively movably clamped on the two side walls 32 of the carrier 3, movably cooperate with the side walls of the carrier, and movably cooperate with the mobile power supply 9. In the embodiment disclosed in the accompanying drawings of the present invention, the clamping blocks 36, the side walls 32 of the carrier, and the mobile power supply 9 elastically cooperate with each other. Specifically, an elastic member such as a spring 37 is arranged between the clamping block 36 and the side wall 32 of the carrier, and the mobile power supply can be clamped between the two side walls of the carrier with a variable clamping force. The elastic member is generally a spring, such as a spring, a tension spring, a leaf spring or an elastomer or other elastic components are also applicable. The elastomer can be made of an elastic material.

[0152] The carrier 3 is shaped like an arch, and the two side walls 32 extend downward respectively. A clamping block 36 is set at the bottom of each of the two side walls 32. The mobile power supply 9 is clamped between the bottom ends of the two side walls 32 of the carrier and is further elastically clamped by the clamping block 36. A groove 320 is set on the side wall 32, and the groove 320 is opened horizontally (or left and right), that is, in the direction of the two sides of the carrier. In specific implementation, the groove 320 can be set on the front and rear end surfaces of the arch side wall (here the front and rear end surfaces are consistent with the direction of the reciprocating movement of the carrier), and is used to accommodate the convex rail of the clamping block 36. When the clamping block 36 is set on the side wall of the carrier, the convex rail of the clamping block 36 is embedded in the groove 320 on the end surface of the side wall: on the one hand, it plays a limiting role on the clamping block 36 to prevent the clamping block from falling out, and on the other hand, it limits the convex rail of the clamping block to slide back and forth in this groove.

[0153] Refer again Fig.12 The two side walls 32 of the carrier extend downward, and the bottom ends thereof form claws 321 , and the grooves 320 are formed on the sides of the claws 321 .

[0154] As an implementation method, Figures 11 to 14 A pair of claws 321 are formed at the bottom of each side wall 32, and a notch 324 is formed between the pair of claws 321 along the side wall. A protruding column 33, such as a cylinder, is provided on the inner wall surface of the side wall 32. A fine convex rib 362 is provided on the side surface of the column 33, and the column 33 is used to string an elastic member such as a spring 37, and the fine convex rib 330 is used for initial limit when the spring 37 is installed.

[0155] The carrier 3 is provided with a threaded hole (not shown), and a screw rod 87 passes through the threaded hole of the carrier 3. The two screws are engaged with each other, so that the screw rod rotates to drive the carrier 3 to reciprocate along the length direction of the screw rod 87. The outer wall surfaces of the two side walls 32 of the carrier are provided with raised guide posts 35 for sliding support of the carrier 3.

[0156] The clamping block 36 is sleeved on the side wall 32 of the carrier 3. As an embodiment, the clamping block 36 is sleeved on the two side walls 32 of the arch of the carrier 3 and surrounds the bottom of the side wall, so that the clamping block 36 as a whole is not easy to deform and loosen. The clamping block 36 sleeved on the left side wall of the carrier and the clamping block 36 sleeved on the right side wall of the carrier are symmetrically arranged.

[0157] An inner cavity 360 is formed inside the clamp block 36. The top of the inner cavity 360 can be open, and an opening (not shown) is correspondingly provided at the bottom for the carrier claw 321 to pass downward. The bottom end of the carrier side wall 32 passes through the inner cavity 360, and the side walls surrounding the inner cavity 360 surround the lower section of the carrier side wall 32. For ease of description, the side walls surrounding the inner cavity 360 are divided into a first side wall 3601 and a second side wall 3602 in the left and right relative directions, and front and rear side walls 3603 and 3604 in the front and rear relative directions. Each side wall is an integral structure, or each side wall can be assembled into an integral structure. The first side wall 3601 is located on the outer side of the outer wall surface of the carrier side wall 32 and can be close to or away from the outer wall surface of the carrier side wall 32. The second side wall 3602 opposite to it is located on the inner side of the inner wall surface of the carrier side wall 32 and is separated from the inner wall surface of the carrier side wall 32 by a certain distance to accommodate the column 33 on the side wall 32 and the spring 37 sleeved thereon. Preferably, the interval is greater than the length of the column 33 on the side wall. Accordingly, the second side wall 3602 can be flexibly matched to move away from or close to the inner wall surface of the carrier side wall 32. The front and rear side walls 3603 and 3604 are respectively located outside the front and rear end surfaces of the carrier side wall 32. Thus, a set structure is formed in which the clamp block 36 surrounds the carrier side wall 32.

[0158] The column 33 on the inner wall surface of the carrier side wall 32 is accommodated in the inner cavity 360 and faces the second side wall 3602 of the clamp block inner cavity 360. A guide slope 362 and a receiving slide groove 363 are provided on the inner wall surface (the wall surface located in the inner cavity 360) of the second side wall 3602 at the position corresponding to the column 33. The guide slope 362 is set to a certain depth downward from the top of the second side wall 3602, and the receiving slide groove 363 is set in the middle of the guide slope 362 and extends to the bottom of the inner cavity 360. The setting of the guide slope 362 and the receiving slide groove 363 facilitates the installation and positioning of the limit spring 37. The second side wall 3602 of the clamp block inner cavity 360 extends downward, and a protrusion 365 is provided on its outer wall surface (located outside the cavity 360 and opposite to its inner wall surface). In the example shown in the figure, the protrusion 365 is an extended flat plate, which is of course not limited to a flat plate structure. The extensions 365 of the two clamping blocks 36 sleeved on the two side walls 32 of the carrier extend relatively and are located below the mobile power supply, and the clamping device is balanced by the lower surface of the mobile power supply. One side of the bottom wall 3605 of the inner cavity 360 abuts against the inner wall surface of the second side wall 3602, and the other side extends toward the direction of the side wall 32 of the carrier to form a supporting surface 364. The supporting surface 364 extends toward the side wall 32 of the carrier and is supported below the end surface of the notch 324 at the bottom of the side wall of the carrier. A rotating shaft 361 is provided on the lower surface of the bottom wall 3605 of the clamping block inner cavity, and a wheel 34 is sleeved on the rotating shaft to facilitate the rolling cooperation of the clamping device 30 on the lower plate track. The front and rear side walls 3603 and 3604 of the clamping block inner cavity 360 extend downward and can extend integrally with the second side wall 3062, and a convex rail 366 is formed on the inner wall surface of the front and rear side surfaces extending downward (the wall surface located on one side of the cavity 360). The protruding rail 366 extends in the left-right direction (ie, is arranged along the width direction of the front and rear sides), and can be embedded in the groove 320 arranged on the side wall 32 of the carrier so that the two form a movable fit in the left-right direction.

[0159] During assembly, the clamping block 36 is sleeved on the side wall 32 of the carrier 3, specifically, the clamping block 36 is sleeved upward from the bottom end of the side wall 32 of the carrier, the claw portion 321 at the bottom end of the side wall of the carrier passes through the bottom wall of the clamping block inner cavity 360, and the groove 320 provided on the side wall 32 is sleeved outside the convex rail 366 of the clamping block 36, that is, the convex rail 366 is inserted into the groove 320 to form a relative sliding or moving fit. In this embodiment, the two claw portions 321 at the bottom end of the side wall of the carrier are respectively abutted against the inner wall surfaces of the front and rear side walls 3603 and 3604 of the clamping block, and the convex rail 366 provided on the inner wall surfaces of the front and rear side walls can be relatively movably inserted into the groove 320 provided on the claw portion 321. The end surface of the notch 324 between the two claw portions 321 abuts against the clamping block supporting surface 364 below. The column 33 is accommodated in the inner cavity 360, and the spring 37 is sleeved on the column 33 set on the side wall of the carrier, and is positioned by the fine ribs 330 on the surface of the column. One end of the spring 37 abuts against the inner wall surface of the side wall of the carrier, and the other end abuts against the inner wall surface of the second side wall 3602 of the clamp block, so that the clamp block 36 and the side wall 32 of the carrier are elastically matched, and the relative displacement between the clamp block 36 and the side wall 32 of the carrier changes with the compression or extension of the spring 37. In a specific embodiment, the width of the inner cavity 360 of the clamp block 36 is larger than the arch side wall 32, so the clamp block 36 can be displaced in the left and right directions relative to the inner and outer wall surfaces of the side wall 32. When there is no mobile power supply, the clamp block 36 will be displaced toward the middle direction of the warehouse channel 63 under the action of the spring 37. When there is a mobile power supply, the clamp block 36 will be displaced away from the middle direction of the warehouse channel 63 under the squeeze of the mobile power supply, and this displacement is adapted to the width of the mobile power supply. The bottom of the clamp block 36 is provided with a rotating shaft 361. After the wheel 34 is assembled, the wheel 34 can rotate around the rotating shaft 361. The outer diameter of the wheel 34 can roll against the side wall of the track 64, thereby reducing the friction between the wheel 34 and the track 64 during relative movement. The inner cavity 360 of the clamp block is provided with a guide slope 362 and a receiving slide 363. The guide slope 363 provides a gap space so that the clamp block can easily surround the spring 37 in the natural state. As the clamp block 36 is continuously pressed in, the spring 37 slides along the guide slope step 367 and gradually enters a compressed state and has elastic force. Since the assembly does not require screws or other fasteners to limit the spring 37, this assembly method is simple to operate. The cooperation of the receiving slide 363 and the guide slope step 367 allows the receiving slide 363 to provide space for the column 33 on the side wall of the arch of the carrier to shift in the receiving slide 363. The height of the column 33 on the carrier and the depth of the accommodating groove 363 of the clamp block 36 are matched in size: in one case, the carrier 3 is close to the charging pin seat 7 and there is no mobile power supply in the warehouse channel 63. The clamp block 36 will move inward to the maximum amount under the action of elastic force, and the outer side surface of the clamp block will be attached to the outer wall of the carrier when the maximum displacement is reached. At this time, the tail end of the column 33 is still located in the accommodating groove 363, ensuring that the spring 37 strung on the column 33 will not fall out from the tail end of the column 33.Another situation is that the carrier 3 is near the warehouse entrance and there is a mobile power supply 9 in the warehouse 63. Especially when the width of the mobile power supply is relatively large, the clamping block 36 will move outward to the maximum amount under the squeezing of the mobile power supply. At this time, the tail end of the column 33 will not interfere with the accommodating groove surface, and ensure that the clamping block 36 still has room for left and right displacement.

[0160] The spring 37 provides elastic force for clamping the mobile power source by applying elastic force on the guide ramp step 367 of the clamp block 36. The supporting surface 364 set in the middle part of the clamp block can correspondingly support the end surface of the notch 324 on the side wall of the carrier arch. This supporting surface 364 can limit the horizontal movement of the clamp block 36 without shaking or tilting. The extension part 365 is set at the bottom end of the clamp block 36. The height of the extension part 365 can be set to be slightly lower than the support rib 62 of the lower plate 60, so that the extension part 365 of the clamp block 36 does not need to share the load-bearing of the mobile power source 9. After the mobile power source is placed, the lower surface of the mobile power source can be used to stabilize the clamp block 36 to prevent the clamp block from tilting at a larger angle.

[0161] The assembled clamping device 30 has two clamping blocks 36 on the left and right, each of which is equipped with a spring 37. The two clamping blocks 36 are pushed by the elastic force to clamp the mobile power supply 9. The mobile power supply 9 can be towed and moved by the clamping force. The clamping force of the clamping device 30 on the mobile power supply 9 can also be adjusted on the Y-shaped track 61 ( Fig.15 ) and the elastic force changes with the different travel positions on the clamp block 36. As an embodiment, the springs 37 used on the clamp block 36 have the same specifications and equivalent elastic force, and the mobile power supply 9 can be adjusted to the center, so that the charging end of the mobile power supply 9 is aligned with the charging pin seat 7 of the main control PCB board 70, and the mobile power supply 9 can also be kept in the center when it is dragged out of the warehouse. This elastic clamping method of the mobile power supply can adapt to the fluctuation of the size of the mobile power supply and has high clamping compatibility with the mobile power supply 9.

[0162] Refer again Fig.15 , a track 64 is provided on the lower plate 60 of the bin body, and the track 64 is arranged in the front-to-back direction of the bin channel 63, which is consistent with the movement direction of the carrier body, and is used to guide the reciprocating movement of the carrier body 3. In this embodiment, two tracks 64 are arranged to form a Y-shape, and the spacing between the tracks increases as they are closer to the bin channel opening, and decreases on the side close to the charging needle seat 7. When the carrier body 3 is in a position close to the bin channel opening, as shown in FIG. Figure 6As shown, the distance between the tracks 64 increases, and the wheels 34 on the clamp block move outwards in close contact with the side walls of the tracks 64. The clamp block 36 squeezes the spring 37 to shorten and share part of the elastic force. At this time, the elastic force of the spring 37 acts partly on the track 64 and partly on the mobile power supply 9, so that the clamping force of the clamp block 36 on the mobile power supply 9 becomes smaller, so that the user can take away the mobile power supply or return the mobile power supply with less force, while ensuring that the clamp block 36 continues to maintain the clamping force on the mobile power supply, which is sufficient to clamp the mobile power supply into the warehouse. When the carrier 3 is in a position close to the charging pin seat, as shown in FIG. Figure 5 As shown in the figure, when the track spacing becomes smaller, the wheel 34 on the clamp block will separate from the side wall of the track, and the clamp block 36 will release the spring length to concentrate the elastic force on the mobile power supply, so that the clamping force of the clamp block on the mobile power supply becomes larger, and the mobile power supply is clamped tighter, which can overcome the spring reaction force of the charging needle seat 7, thereby clamping the mobile power supply 9 to keep it in the charging position.

[0163] The spring force of the clamping device 30 changes according to the position of the track 61 to which it belongs, and plays different roles: for example, when the user needs to return and put the mobile power supply into the warehouse channel 63, the elastic force of the clamping device 30 becomes smaller, and the user only needs a small force to return the mobile power supply 9 into the warehouse channel 63. For example, when the user needs to rent and take away the mobile power supply, the elastic force of the clamping device 30 becomes smaller, and the user only needs a small force to take the mobile power supply 9 out of the warehouse channel 63. When the clamping device 30 is towing the mobile power supply or the mobile power supply is returned to the warehouse channel for charging, its elastic force becomes larger, which can overcome the small spring reaction force on the charging needle seat, and can provide a larger clamping force to the mobile power supply to keep the mobile power supply in the charging position.

[0164] The output shaft of the motor 8 is connected to the screw 87 to drive the screw 87 to rotate. The screw 87 is connected to and drives the carrier 3 to move back and forth in the warehouse channel 63. The carrier 3 is slidably supported on the warehouse body 6.

[0165] As a modified embodiment, the matching structure of the clamp block 36 and the lower end of the carrier side wall can be interchanged, for example, a column 33 is provided on the clamp block 36, and a spring 37 is sleeved on the column 33. A guide slope 362 and a receiving slot 363 can be correspondingly provided on the carrier side wall to match the spring.

[0166] The protruding rail 366 can be disposed on the carrier side wall 32 , and the groove 320 is disposed on the clamping block 36 , and the protruding rail 366 is embedded in the groove 320 for relative sliding cooperation between the two.

[0167] In other embodiments, the spring 37 is directly replaced by other elastic members such as springs, tension springs, leaf springs or elastomers or other elastic components. Whether the column 33 needs to be set is determined according to the strength of the springs, tension springs, leaf springs or elastomers. The two ends of the elastic member are respectively pressed against the clamping block and the side wall 32 of the carrier so that the two are elastically matched, and the elastic member can be compressed or released to move closer to or away from each other, so that the clamping device 30 as a whole is elastically clamped between the two sides of the mobile power supply, which can be adjusted according to the width of the mobile power supply or according to the spacing width between the rails on the lower plate 60.

[0168] An embodiment of the present invention also provides a mobile power module control method, which performs at least one of the following steps:

[0169] Opening point stroke control steps: control the carrier to carry the mobile power out of the warehouse, and the carrier is linked to open the warehouse door to provide mobile power;

[0170] Closing point travel control steps: control the carrier to move inward, close the warehouse door in linkage, and seal the warehouse passage;

[0171] Placement point travel control: Control the carrier to open the door, sense the mobile power supply to be placed in the warehouse for a predetermined distance and control the carrier to move backward until the carrier reaches the closing point and stops, then control the carrier to close the door;

[0172] Timeout control: When the mobile power supply stops temporarily in the warehouse for a preset time and is not taken away, the carrier is controlled to move inwards, drag the mobile power supply back into the warehouse, and the warehouse door is closed to seal the warehouse.

[0173] As a further implementation, the mobile power module control method is specifically:

[0174] In the opening point stroke control step: controlling the carrier to carry the mobile power source out of the warehouse, the carrier is linked to release the lock arm and release the restriction on the mobile power source, and the carrier is linked to open the warehouse door to provide the mobile power source;

[0175] In the closing point stroke control step: controlling the carrier to move inward, linking the locking arm to be in an empty warehouse locking state and linking the warehouse door to close the warehouse passage;

[0176] In the step of controlling the insertion point, the carrier is controlled to open the warehouse door in linkage, the locking arm of the carrier is controlled to reset and raise, the mobile power supply is placed in the warehouse aisle by a predetermined distance and the carrier is controlled to move backward until the carrier reaches the closing point and stops, and then the carrier is controlled to close the warehouse door in linkage, and the locking arm of the carrier is controlled to swing down to lock the end of the mobile power supply and put it in a charging position; in the step of overtime control, after the mobile power supply is temporarily stopped in the warehouse aisle for a preset time and is not taken away, the carrier is controlled to move inward, the mobile power supply is dragged back into the warehouse aisle, the locking arm is tightened in linkage to lock the mobile power supply, the mobile power supply is locked in the charging position, the warehouse door is closed in linkage, and the warehouse aisle is closed.

[0177] The mobile power module control method of the present invention, wherein in the opening point stroke control step, the control motor drives the transmission device to push the carrier to drag the mobile power forward until the mobile power extends out of the warehouse door by a predetermined distance, and the carrier touches the opening point sensor and stops. In the closing point stroke control step, the control motor reversely rotates to drive the transmission device to push the carrier backward until the carrier touches the closing point sensor and stops.
