Description

Technical Field

[0001] The invention relates to a mobile power charging device, in particular to a warehouse door opening and closing device and a mobile power charging module thereof. Background Art

[0002] The existing mobile power rental equipment or mobile power charging modules have different doors. Generally, an additional motor is required to drive the door to rise and open and fall and close. The mobile power will be absorbed inside the warehouse. Therefore, the mobile power charging module must use two motors, one motor is used to drive the door to rise and fall, and the other motor drives the rolling shaft to rotate. The opening and closing of the door requires a separate motor drive, Hall switch, wires and other accessories, and a separate program is required to drive the motor and a separate sensor to judge the state of the door, which increases the cost.

[0003] There are also other mobile power rental equipment or mobile power charging module doors that rely on torsion springs to push the revolving door inward to open and outward to close. The mobile power is partially absorbed in the warehouse and partially exposed outside the door. When the mobile power is absorbed in the warehouse, its end squeezes the revolving door and stops at the position of the revolving door. The revolving door is stuck and cannot be rotated to close the door, causing the end of the mobile power to be exposed outside the door, which is prone to dust accumulation or the risk of being directly hit during transportation, which is not conducive to protecting the mobile power with charging terminals at both ends.

[0029] It should be noted that, in the absence of conflict, the various embodiments in the present application and the features in the embodiments may be combined with each other. The present invention is further described in detail below in conjunction with the drawings and specific embodiments.

[0030] Reference Figures 1 to 8A mobile power charging module 100 includes a warehouse body 20 for absorbing and charging a mobile power supply, and the warehouse body 20 includes a warehouse passage 21 formed inside and a side wall 6 around the warehouse passage. A warehouse door 5 is provided at the front end of the warehouse body 20, and a charging seat 7 for charging a mobile power supply 9 is provided on the side wall inside the warehouse passage. It can be understood that the charging seat 7 is provided on the corresponding side wall of the warehouse body according to the position of the charging terminal on the mobile power supply. The warehouse passage 21 is used to accommodate the mobile power supply 9 and allow the mobile power supply 9 to enter, exit and charge. The warehouse door 5 is provided as a warehouse opening, which is used as an entrance and / or exit of the mobile power supply for putting in and / or taking out the mobile power supply, and the warehouse opening is connected with the warehouse passage 21. A carrier 3 of the mobile power supply is provided in the warehouse passage 21, and the carrier 3 carries the mobile power supply 9 in and out of the warehouse passage 21, so that the mobile power supply 9 can be sucked in for charging or sent out for use.

[0031] Refer again Figures 1 to 4 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 20. The opening and closing device is a linkage opening and closing device, including a linkage 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 20, and the crank 55 is movably installed on the warehouse body 20. 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 opening.

[0032] The mobile power charging module 100 can carry the mobile power 9 in and out of the warehouse passage 21 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 21, 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, thus providing closed protection for the mobile power module 100 and the mobile power 9. The mobile power in and out of the warehouse passage 21 drives the door to open or close through the linkage device, specifically, the mobile power in and out activity is performed and completed through the reciprocating motion of the carrier 3, so the reciprocating motion of the carrier 3 drives the door to open or close through the linkage device.

[0033] 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.

[0034] In this embodiment, the door 5 is configured as a sliding door, which can be installed at the front end of the warehouse body 20 to slide up and down to open or close the warehouse opening. 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 bump, a latch, etc. or other sliding support structures, which can slide relative to the slide groove. Figure 4 In the embodiment shown, the front ends of the left and right side walls of the warehouse body are provided with slide grooves 64, and the two sides of the warehouse door 5 are provided with slide rails 54. 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 64 for sliding cooperation. It can be understood that the slide rails and the 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 20, and the slide grooves are arranged at 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 ( Figure 1 ) 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.

[0035] Refer again Figure 3The 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 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 20, and is further elastically fixed to the warehouse body 20 by the elastic member tension spring 4. The crank 55 is driven to move on the warehouse body through the elastic force of the side 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 20 can be achieved by the movable or fixed cooperation between the connecting shaft and the shaft hole or the connecting structure. The position setting of the connecting shaft and the shaft hole is interchangeable. The crank 55 is connected to the door 5 by the matching connection between the mushroom head latch 51 as the connecting shaft and the slide slot 551 as the shaft hole. The latch 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 crank 55 is connected to the connecting rod 2 by the matching connection between the mushroom head latch 552 as the connecting shaft and the slot 29. The latch 552 can rotate or move relatively in the slot 29, so that the crank 55 is driven by the connecting rod 2. The crank 55 is connected to the warehouse body 20 by 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. The mushroom head structure is used for limiting, the same below.

[0036] 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.

[0037] Correspondingly, a rotating shaft 65 and a screw hole boss 63 are correspondingly arranged on the side wall 6 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.

[0038] The shaft hole 550 of the crank 55 is mounted on the shaft 65 of the side wall 6 of the bin body (where the shaft 65 and the shaft hole 550 are interchangeable), the front end elliptical slide groove 551 is mounted on the mushroom head latch 51 of the sliding bin door 5 (the latch 51 and the slide groove 551 are interchangeable), the rear end mushroom head latch 552 is inserted into the slot 29 of the connecting rod 2 (the latch 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 63 on the side wall 6 ( Figure 2 ) and clamp the two ends of the tension spring with screws.

[0039] 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 21 along the direction of the mobile power supply entering and exiting. Preferably, the connecting rod 2 is placed in the slide groove 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 on 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.

[0040] 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 to simultaneously carry the mobile power 9 back and forth and link the rising and falling movements of the sliding door 5. The single motor can reduce the cost of electronic components of the module and simplify the structure.

[0041] Please refer again Figure 4 The mobile power charging module 100 of the embodiment of the present invention includes a motor 8, which is installed on the warehouse body 20. A support structure 22 is further provided in the warehouse body, and the support structure 22 is located at the front end of the warehouse channel 21, behind the warehouse door 5, and above the mobile power inlet and outlet, which can be a cross structure. The motor 8 is installed in the support structure 22 and covered by the motor cover 83. 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 and drives the carrier 3 to reciprocate. In a specific embodiment, a threaded hole (not shown) is provided on the carrier 3, and the screw 87 passes through the threaded hole of the carrier 3. The screw 87 is threadedly matched between the two, so that the carrier 3 is driven to reciprocate along the length direction of the screw 87 by rotating the screw. The motor 8 is installed on the front support structure 22 of the warehouse body, the front end of the screw 87 is rotationally matched with the output shaft of the motor 8, and the rear end is rotationally inserted into the shaft hole (not shown) provided on the rear wall of the warehouse body, and the carrier 3 is passed through the screw 87 and driven by the screw to reciprocate. The mobile charging module 100 is further provided with a main control 70, which 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 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), and the charging needle seat passes through the charging 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. The charging module 100 is further provided with a micro switch 86, and the main control 70 controls the motor 8 through the micro switch 86.

[0042] The carrier 3 is driven by the screw 87 to move straight back and forth in the warehouse passage 21. Its structure can be set on the support structure at the top and / or bottom of the warehouse passage, 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. The carrier 3 is provided with a clamping portion 39 for clamping the mobile power supply 9 to support and carry the mobile power supply 9 in and out of the warehouse passage 21. The carrier 3 and the warehouse body are connected by a sliding matching structure 30 (such as Figure 2 ), so that the carrier 3 is slidably supported on the warehouse body 20. The sliding matching structure 30 can be the matching between the slider and the slide groove. In this embodiment, the slide groove is set on the side wall of the warehouse body. The end of the carrier 3 is a pushing end face 31. The linkage connecting rod 2 is inserted into the carrier 3. 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 the carrier 3 is pushed and pulled to the rear of the warehouse body, thereby driving the connecting rod 2 to pull backward.

[0043] The sliding door 5 is opened and the mobile power supply 9 is rented:

[0044] 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 the 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 21 for the user to take the mobile power supply away.

[0045] 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.

[0046] The process of opening the sliding compartment 5 and returning the mobile power supply 9:

[0047] 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 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 passage 21.

[0048] 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.

[0049] The above reciprocating motion of the carrier 3 is driven by the motor 8, which can simultaneously carry out the reciprocating motion of the mobile power source and the rising and falling motion of the sliding door 5 in linkage. The mobile power charging module 100 can carry the mobile power source 9 in and out of the warehouse passage 21 and charge the mobile power source 9. While carrying the mobile power source 9, the sliding door 5 can be opened and closed in linkage with the connecting rod 2, that is, when there is a mobile power source in the warehouse passage or not, the sliding door 5 can be in a normally closed state, which provides a closed protection for the mobile power source module and the mobile power source.

[0050] Refer again Figure 5-8 Furthermore, 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 21.

[0051] 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 20, located at the front end of the warehouse passage and behind the warehouse door 5, and can lock or unlock the mobile power in the warehouse passage.

One end of the tension spring 4 is installed on the locking arm 1, and the other end is installed on the support structure 22, so that it elastically expands and contracts between the locking arm 1 and the support structure 22 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 pulled backward or pushed, the rebound force of the tension spring 4 pulls the locking arm 1 upward until it is unlocked.

[0053] 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 Figure 3 When the locking arm 1 is pulled downward 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 seat on the rear wall of the charging module, and charging can be performed.

[0054] 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.

[0055] The locking arm is provided with a rotating shaft 13, and a beak 23 is correspondingly provided on the front end support structure 22 of the warehouse channel, and a rotating shaft hole 230 is provided on the beak 23. The rotating shaft 13 of the locking arm is rotatably installed in the beak rotating shaft hole 230 of the support structure 22, 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 23 installed on the support structure 22 is located between the two limiting surfaces 15, and the rotating shaft 13 is penetrated in the beak rotating shaft hole 230 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 22 and can swing around this rotating shaft hole. In this embodiment, the beak rotating shaft hole 230 is a hole with an open top, forming a rotating support for the rotating shaft 13.

[0056] 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 beak 23 of the supporting structure 22. 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 beak shaft hole 230 of the supporting structure 22, an assembly space is formed between the two parallel limiting surfaces 15 to accommodate the beak 23 of the supporting structure 22, which can avoid interference during the swinging process, and the structural coordination is relatively compact.

[0057] 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.

[0058] 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.

[0059] As an embodiment, the front end 25 of the connecting rod 2 is provided with a pin 28 protruding vertically, and the pin 28 is installed in the arc groove 14 of the locking arm 1 in a tensioned and movable manner. The protruding pin 28 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 28 being clamped on the outside of the slot 14. The pin 28 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 28 is installed in the slot hole 29. In an embodiment of the present invention, the pin shaft 28 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.

[0060] 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 28 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 28 in the arc-shaped groove 14.

[0061] The pin shaft 28 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 shaft 27 on the rear end 26 can be pressed against by the carrier 3 and pushed backward.

[0062] 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.

[0063] 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 21, passes through the carrier 3, and the rear end 26 is pushed by the carrier 3.

[0064] 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.

[0065] The support structure 22 is vertically arranged at the front end of the warehouse channel 21, above the entrance of the mobile power supply. The eagle beak 23 arranged on the support structure 22 extends backward between the two parallel limiting surfaces 15 of the locking arm 1, and the top forms an eagle beak shaft hole 230 to rotatably support the shaft 13 of the locking arm 1. The support structure 22 extends forward to form a screw hole 24 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.

[0066] 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 24 of the supporting structure 22. The tension spring expands and contracts accordingly as the locking arm 1 swings.

[0067] 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 realizes the tightening or loosening of the locking arm 1 through the arc groove 14, and can apply a tightening force to 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.

[0068] 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 21. When the carrier 3 moves back and forth, the linkage link 2 pulls the locking arm 1 to swing around the rotating shaft 13. When the locking arm 1 swings upward, it performs an unlocking action on the end of the mobile power supply. When the locking arm 1 swings downward, it performs a locking action on the end of the mobile power supply until the charging terminal of the mobile power supply presses the charging seat spring of the module to retract a certain distance. When the carrier 3 runs to the position and stops, the link 2 and the locking arm 1 swing accordingly and stop. The locking arm 1 still keeps the tension on the end of the mobile power supply, thereby limiting the space for the mobile power supply 9 to retreat, so that the mobile power supply 9 remains in the charging contact position, and the locking force is relatively reliable.

[0069] Lock arm opening and mobile power lending process:

[0070] 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 21 for the user to take the mobile power supply away.

[0071] 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.

[0072] Lock arm opening and mobile power supply return process:

[0073] 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 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.

[0074] 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.

[0075] The rotational cooperation between the locking arm 1 and the supporting structure 22 may also be achieved by disposing the rotating shaft 13 on the supporting structure 22 , and correspondingly, the rotating shaft hole 230 is disposed on the limiting surface 15 of the locking arm 1 .

[0076] Similarly, the connecting rod 2 and the locking arm 1 can be flexibly matched, and the protruding pin 28 can also be provided on the locking arm 1 , while the arc-shaped slot 14 is provided on the connecting rod 2 .

[0077] 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.

[0078] 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.

[0079] 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 seat 7 is arranged at a corresponding position of the side wall of the warehouse body 20. The locking device 10 can be arranged at the front or rear end of the warehouse or at other suitable positions to lock the end of the mobile power supply.

[0080] 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 21, 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.

[0081] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of protection of the present invention is defined by the appended claims and their equivalents.
