Description

Technical Field

[0001] This invention relates to the field of battery swapping equipment technology, specifically a battery swapping device for shared electric vehicles. Background Technology

[0002] With the deep integration of the sharing economy and the concept of green travel, two-wheeled electric vehicles have become the core means of transportation for short-distance urban travel, and are widely used in various scenarios such as daily commuting, instant food delivery, and last-mile delivery of express packages. With the continuous expansion of the industry, the demand for efficiency, safety and convenience of electric vehicle energy replenishment is constantly upgrading, which is driving the energy replenishment technology to evolve from the traditional charging mode to the standardized and intelligent battery swapping mode. Shared electric vehicle battery swapping devices have emerged and are gradually becoming the mainstream energy replenishment solution in the industry.

[0003] Chinese patent CN121084243A discloses a shared battery charging and swapping cabinet with temperature adaptive control function. The heating mechanism enables adaptive switching of the temperature transmission path between adjacent battery compartments. Under normal conditions, the temperature transmission path between adjacent battery compartments remains connected, and the heat between adjacent battery compartments is mutually transferred.

[0004] The above method can utilize the residual heat during charging to heat the low-temperature battery and improve charging efficiency. However, it has a complex structure and lacks an effective heat dissipation mechanism in high-temperature environments, which can easily lead to thermal runaway during battery charging, posing safety hazards and greatly reducing the charging efficiency of the battery. This makes it difficult to meet the actual needs of efficient and safe battery swapping for shared electric vehicles. Summary of the Invention

[0005] To solve the above technical problems, the present invention is implemented through the following technical solution: a shared electric vehicle battery replacement device, including a battery swapping cabinet, a support frame fixedly connected to the top of the battery swapping cabinet, a rain shelter fixedly connected to the top of the support frame, a charging compartment evenly penetrating and fixedly connected to the side of the battery swapping cabinet, a heat exchange box penetrating and fixedly connected to one side of the inner wall of the battery swapping cabinet, both sides of the heat exchange box being fixedly connected to the charging compartment, an air filter assembly penetrating and fixedly connected to the top of the charging compartment, a charging mechanism fixedly connected to one side of the charging compartment, a switching assembly fixedly connected to the bottom of the inner wall of the charging compartment, a first sliding groove and a second sliding groove respectively opened on the side of the battery swapping cabinet located on both sides of the charging compartment, a lead screw rotatably connected to the top and bottom of the inner wall of the first sliding groove, a guide rod fixedly connected to the top and bottom of the second sliding groove, a slider sleeved on the guide rod and the lead screw, the slider being threadedly connected to the lead screw, the slider being slidably connected to the guide rod, a drive motor fixedly connected to the top of the battery swapping cabinet, the drive shaft of the drive motor extending into the first sliding groove and fixedly connected to the lead screw, and a receiving and transporting assembly fixedly connected to one side of the slider.

[0006] Preferably, the receiving and transporting component includes a receiving box, an elastic buffer pad is fixedly connected to the bottom of the inner wall of the receiving box, a receiving seat is fixedly connected to the top of the elastic buffer pad, a receiving groove is provided on the top of the receiving seat, a fixed end of a first electric telescopic rod is fixedly connected to the side of the receiving box, the movable end of the first electric telescopic rod passes through the receiving box and is fixedly connected to a first push plate, and the receiving box is fixedly connected to one side of the slider.

[0007] Preferably, a placement slot is fixedly connected to the side of the charging compartment, and a second push plate is slidably connected to the inner wall of the placement slot. A fixed end of a second electric telescopic rod is fixedly connected to the side of the charging compartment, and the movable end of the second electric telescopic rod extends into the placement slot and is fixedly connected to the second push plate. When replacing the battery, the user places the battery into the receiving slot of the receiving seat. The elastic buffer pad cushions the impact and prevents the battery from falling. The drive motor is started to drive the lead screw to rotate, and the slider moves along the lead screw, guide rod and sliding groove to send the receiving and transporting component to the corresponding charging compartment height. The first electric telescopic rod is started to push the first push plate to push the battery into the charging compartment. When a new battery is taken out, the drive motor sends the receiving and transporting component to the side of the corresponding charging compartment. The second electric telescopic rod is started to push the second push plate to push the new battery in the placement slot to the receiving and transporting component for the user to take out.

[0008] Preferably, a thermal expansion member is fixedly connected to the bottom of the inner wall of the charging compartment, a trigger switch is fixedly connected to the top of the thermal expansion member, and a heat exchange port is opened on one side of the inner wall of the charging compartment.

[0009] Preferably, the heat exchange box has heat exchange connecting pipes evenly connected to its side, and the heat exchange box has an air outlet for a cold air blower connected to its side. The drive signal for the cold air blower is controlled by the trigger switch, and the heat exchange connecting pipes are fixedly connected to the inner wall of the heat exchange port.

[0010] Preferably, the switching assembly includes a first heat-conducting plate, with symmetrical through holes on the top of the first heat-conducting plate, and a second heat-conducting plate fixedly connected to the portion of the top of the first heat-conducting plate located on both sides of the through holes. An elastic guide plate is fixedly connected to one side of the second heat-conducting plate, a trigger rod is fixedly connected to the bottom of the first heat-conducting plate, a first spring is uniformly fixedly connected to the bottom of the first heat-conducting plate, a switching plate is fixedly connected to the portion of the bottom of the first heat-conducting plate located on one side of the first spring, and a connecting opening is uniformly opened on the side of the switching plate. A wind baffle is fixedly connected to the bottom of the switching plate.

[0011] Preferably, the bottom of the first spring is fixedly connected to the top of the inner wall of the charging compartment, the connecting port is connected to the heat exchange port, the first heat-conducting plate is slidably connected to the inner wall of the charging compartment, and the side of the elastic guide plate is provided with rounded corners. When the battery is charging, gravity squeezes the first heat-conducting plate, causing the switching plate and the wind baffle to move down, so that the connecting port and the heat exchange port are connected. The heat generated during charging heats the air in the compartment. The heat is transferred to the air below through the first and second heat-conducting plates. The preheated air enters the heat exchange box for heat storage through the heat exchange port and the connecting pipe. When the low-temperature battery enters the adjacent charging compartment, the air duct is opened in the same way, and the residual heat in the heat exchange box enters the charging compartment to preheat the low-temperature battery to shorten the charging preparation time. When the temperature of the charging compartment is too high, the thermal expansion component expands and pushes the trigger switch to touch the trigger rod, starting the cold air fan. The cold air enters the charging compartment through the heat exchange box and the connecting pipe to cool down. After the temperature drops to a suitable range, the thermal expansion component contracts, and the cold air fan stops working.

[0012] Preferably, the air filtration assembly includes an air filtration box, an inclined filter plate fixedly connected to the top of the air filtration box, an air filter plate fixedly connected to the inner wall of the air filtration box, air filter holes evenly distributed on the top of the air filter plate, silica gel desiccant filled between the air filter plate and the inclined filter plate, a rotating shaft evenly penetrating and rotatably connected to the top of the air filter plate, an arc-shaped drive blade fixedly connected to the bottom side of the rotating shaft, and a stirring rod evenly fixedly connected to the part of the rotating shaft above the air filter plate. The bottom of the air filtration box is open, and the air filtration box penetrates the top of the battery swapping cabinet and is fixedly connected to the battery swapping cabinet. When the air cooler is working, external gas enters through the bottom opening of the air filtration box, first passing through the inclined filter plate to initially filter dust and impurities. The impurities slide down the inclined plate surface to the outside of the cabinet. The filtered gas enters between the inclined filter plate and the air filter plate, comes into contact with the silica gel desiccant for dehumidification, and the gas flow drives the arc-shaped drive blade to rotate, which in turn drives the rotating shaft and stirring rod to rotate, turning the silica gel desiccant to ensure full contact with the gas and improve the drying effect.

[0013] Preferably, the charging mechanism includes a connecting frame, a fixed rod fixedly connected to the inner wall of the connecting frame, a rotating rod sleeved on and rotatably connected to the fixed rod, a first U-shaped frame and a second U-shaped frame rotatably connected to both ends of the rotating rod respectively, a second spring fixedly connected to the bottom end of the rotating rod near the first U-shaped frame, an actuating rod fixedly connected to the side of the first U-shaped frame away from the rotating rod, a sliding rod fixedly connected to the side of the second U-shaped frame away from the rotating rod, a charging head fixedly connected to the end of the sliding rod away from the second U-shaped frame, the connecting frame fixedly connected to one side of the charging compartment, and the second spring... The end away from the rotating rod is fixedly connected to one side of the charging compartment. Both the trigger rod and the sliding rod pass through one side of the charging compartment and are slidably connected to it. When the rechargeable battery is placed in the charging compartment, it is guided and positioned by the elastic guide plate and slides between the first and second heat-conducting plates. The battery squeezes the trigger rod, pushing the first U-shaped frame and the rotating rod to rotate around the fixed rod. Through the lever principle, the second U-shaped frame, the sliding rod, and the charging head move towards the battery, so that the charging head is inserted into the battery interface to achieve automatic charging. When the battery is removed after charging is complete, the battery is disengaged from the trigger rod, the second spring drives the rotating rod to rotate in the opposite direction, and the charging head resets and separates from the battery interface.

[0014] This invention provides a battery replacement device for shared electric vehicles. It has the following advantages: 1. This shared electric vehicle battery replacement device features an elastic buffer pad at the bottom of the receiving seat that effectively cushions accidental slippage and impact during battery placement, preventing battery damage. A drive motor, along with a lead screw and guide rod, precisely lifts and lowers the receiving and transporting components to the corresponding charging compartment height. An electric telescopic rod then automatically pushes the battery in and removes it, eliminating the need for manual handling and lifting. This solves the problem of vulnerable groups being unable to replace batteries due to insufficient strength, enabling safe battery replacement and improving battery charging efficiency.

[0015] 2. This shared electric vehicle battery swapping device can recover the heat generated during battery charging in the charging compartment, preheating the low-temperature battery to be charged, shortening the charging preparation time, and improving charging efficiency. When the temperature inside the charging compartment is too high, the thermal expansion component will automatically trigger the start of the cooling fan to circulate cold air into the compartment to cool it down. After the temperature drops to a suitable range, the cooling fan will automatically stop. No manual intervention is required throughout the process, which avoids high-temperature runaway during battery charging, prevents high-temperature damage to the battery, and ensures the safety and stability of the charging process after battery swapping.

[0016] 3. In this shared electric vehicle battery replacement device, the external air drawn in by the cooling fan is first filtered by an inclined filter plate to intercept dust and impurities. The impurities can slide down the plate to avoid clogging the filter structure. Then, the silica gel desiccant absorbs the moisture in the air. The air flow drives the arc-shaped transmission blades and stirring rod to rotate, which makes the silica gel desiccant fully agitate, increases the contact area with the air and the drying effect, and ensures that the air entering the charging compartment is dry and free of impurities. This ensures that the battery is in a dry and clean environment when it is charging and cooling down, thereby improving the battery charging efficiency.

[0017] 4. In this shared electric vehicle battery replacement device, when the battery is placed in the charging compartment, the elastic guide plate can guide and position it. After the battery squeezes the touch rod, the charging head is automatically inserted into the battery interface through lever transmission, realizing automatic charging connection. When the battery is removed, the pressure of the touch rod disappears, and the spring drives the charging head to reset and separate. There is no need to manually plug and unplug the charging head, which improves the convenience and automation of charging operation, effectively avoids the occurrence of charging leakage problems, and makes battery swapping safer and more efficient.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] For the first embodiment, please refer to... Figures 1-5This invention provides a technical solution: a shared electric vehicle battery replacement device, including a battery swapping cabinet 1, a support frame 2 fixedly connected to the top of the battery swapping cabinet 1, a rain shelter 3 fixedly connected to the top of the support frame 2, a charging compartment 4 evenly penetrating and fixedly connected to the side of the battery swapping cabinet 1, a heat exchange box 5 penetrating and fixedly connected to one side of the inner wall of the battery swapping cabinet 1, both sides of the heat exchange box 5 being fixedly connected to the charging compartment 4, a filter assembly 6 penetrating and fixedly connected to the top of the charging compartment 4, a charging mechanism 7 fixedly connected to one side of the charging compartment 4, a switching assembly 8 fixedly connected to the bottom of the inner wall of the charging compartment 4, a first sliding groove 9 and a second sliding groove 10 respectively opened on the side of the battery swapping cabinet 1 located on both sides of the charging compartment 4, a lead screw 11 rotatably connected to the top and bottom of the inner wall of the first sliding groove 9, a guide rod 12 fixedly connected to the top and bottom of the second sliding groove 10, a slider 13 sleeved on both the guide rod 12 and the lead screw 11, the slider 13 being threadedly connected to the lead screw 11, and the slider 13 being slidably connected to the guide rod 12, the top of the battery swapping cabinet 1 being fixedly connected to the lead screw 11, and the charging compartment 4 being fixedly connected to the charging compartment 4, a first sliding groove 9 and a second sliding groove 10 respectively, the top of the battery swapping cabinet 1 being fixedly connected to the lead screw 11, a rain shelter 3 being threadedly connected to the lead screw 11, and the slider 13 being slidably connected to the guide rod 12, the top of the battery swapping cabinet 1 being fixedly connected to the lead screw 11, a heat exchange box 5 being fixedly connected to the inner wall of the charging compartment 4 A drive motor 14 is connected, and the drive shaft of the drive motor 14 extends into the first slide groove 9 and is fixedly connected to the lead screw 11. A receiving and conveying assembly 15 is fixedly connected to one side of the slider 13. The receiving and conveying assembly 15 includes a receiving box 151. An elastic buffer pad 152 is fixedly connected to the bottom of the inner wall of the receiving box 151. A receiving seat 153 is fixedly connected to the top of the elastic buffer pad 152. A receiving groove 154 is opened on the top of the receiving seat 153. The fixed end of the first electric telescopic rod 155 is fixedly connected to the side of the receiving box 151. The movable end of the first electric telescopic rod 155 passes through the receiving box 151 and is fixedly connected to the first push plate 156. The receiving box 151 is fixedly connected to one side of the slider 13. A placement groove 41 is fixedly connected to the side of the charging compartment 4. A second push plate 42 is slidably connected to the inner wall of the placement groove 41. The fixed end of the second electric telescopic rod 43 is fixedly connected to the side of the charging compartment 4. The movable end of the second electric telescopic rod 43 extends into the placement groove 41 and is fixedly connected to the second push plate 42.

[0022] When the battery of a shared electric vehicle needs to be replaced, the user places the battery in the receiving groove 154 on the receiving seat 153. To prevent the battery from slipping and breaking, the elastic buffer pad 152 at the bottom of the receiving seat 153 provides good cushioning and effectively protects the battery from accidental damage. Then, the drive motor 14 is started, which drives the lead screw 11 to rotate. Since the slider 13 is threadedly connected to the lead screw 11 and slidably connected to the guide rod 12, under the rotation of the lead screw 11, the slider 13 moves upward along the first slide groove 9 and the second slide groove 10, thereby moving the receiving and transporting component 15 to the height position corresponding to the charging compartment 4. Next, the first electric telescopic rod 155 is activated, which pushes the first push plate 156 to push the battery in the receiving slot 154 into the charging compartment 4. When a new battery needs to be retrieved, the drive motor 14 first lifts the receiving and transporting component 15 to the side of the corresponding charging compartment 4, and then the second electric telescopic rod 43 is activated. The second electric telescopic rod 43 pushes the second push plate 42 to push the new battery in the placement slot 41 into the receiving and transporting component 15. At this time, the user can easily take out the new battery from the charging compartment 4 for use, avoiding the problem that the weak cannot easily replace the battery due to insufficient strength. The whole process is simple to operate and greatly improves the user experience.

[0023] For the second embodiment, please refer to... Figures 1-8 Based on the first embodiment, the present invention provides a technical solution: a thermal expansion member 44 is fixedly connected to the bottom of the inner wall of the charging compartment 4, and a trigger switch 45 is fixedly connected to the top of the thermal expansion member 44. A heat exchange port 46 is opened on one side of the inner wall of the charging compartment 4. A heat exchange connecting pipe 51 is evenly connected to the side of the heat exchange box 5. An air outlet of a cold air blower 52 is connected to the side of the heat exchange box 5. The drive signal of the cold air blower 52 is controlled by the trigger switch 45. The heat exchange connecting pipe 51 is fixedly connected to the inner wall of the heat exchange port 46. The switching component 8 includes a first heat-conducting plate 81. Through holes 82 are symmetrically opened on the top of the first heat-conducting plate 81. The portions of the top of the first heat-conducting plate 81 located on both sides of the through holes 82 are fixed. A second heat-conducting plate 83 is connected, and an elastic guide plate 89 is fixedly connected to one side of the second heat-conducting plate 83. A trigger rod 84 is fixedly connected to the bottom of the first heat-conducting plate 81. A first spring 85 is evenly fixedly connected to the bottom of the first heat-conducting plate 81. A switching plate 86 is fixedly connected to the part of the bottom of the first heat-conducting plate 81 located on one side of the first spring 85. A connecting port 87 is evenly opened on the side of the switching plate 86. A wind baffle 88 is fixedly connected to the bottom of the switching plate 86. The bottom of the first spring 85 is fixedly connected to the top of the inner wall of the charging compartment 4. The connecting port 87 is connected to the heat exchange port 46. The first heat-conducting plate 81 is slidably connected to the inner wall of the charging compartment 4. The elastic guide plate 89 has rounded corners on its side.

[0024] During use, the battery in the charging compartment 4, which is currently charging, sits on the first heat-conducting plate 81. The weight of the battery compresses the first heat-conducting plate 81, causing the switching plate 86 and the wind baffle 88 to move downwards, connecting the connecting port 87 with the heat exchange port 46. As charging progresses, heat is generated, heating the air inside the compartment. This heated air flows through the through-hole 82 to the area below the first heat-conducting plate 81. Furthermore, the second heat-conducting plate 83, being in close contact with the charging battery, transfers heat from the surface of the charging battery to the charging compartment. The heat is transferred to the first heat-conducting plate 81, further transferring the temperature to the area below it. The preheated air flows through the heat exchange port 46 into the heat exchange connecting pipe 51, and finally enters the heat exchange box 5 for heat storage. When a battery with a lower temperature that needs charging enters the adjacent charging compartment 4, the first heat-conducting plate 81 is pressed downward by the battery, causing the switching plate 86 and the wind baffle plate 88 to move downward, so that the connecting port 87 connects with the heat exchange port 46, allowing the heat stored in the heat exchange box 5 to be transferred through the heat exchange connecting pipe 51 and heat exchange. The airflow enters from the port 46 below the first heat-conducting plate 81 in the adjacent charging compartment 4, and finally flows through the through hole 82 to the surface of the battery that needs charging, which has a lower temperature, to preheat it. This shortens the battery's charging preparation time and improves charging efficiency. At the same time, when the temperature inside the charging compartment 4 is too high, the thermal expansion component 44 will expand due to heat, causing the trigger switch 45 to move upward and press against the trigger rod 84 at the bottom of the first heat-conducting plate 81, thereby triggering the start of the cold air blower 52. The cold air blows cold air into the heat exchange box 5 through the air outlet. The heat exchange connecting pipe 51 and the heat exchange port 46 enter the charging compartment 4 to cool the high-temperature air inside the charging compartment 4, thereby reducing the temperature inside the charging compartment 4 and preventing damage to the battery due to excessive temperature. This ensures the safety and stability of the battery charging process. When the temperature inside the charging compartment 4 drops to a suitable range, the thermal expansion component 44 contracts, the trigger switch 45 separates from the trigger rod 84, and the cooling fan 52 stops working. The entire temperature regulation process is completed automatically without manual intervention, which improves the intelligence and ease of use of the battery swapping cabinet 1.

[0025] Third embodiment, please refer to Figures 1-10 Based on the second embodiment, the present invention provides a technical solution: the air filtration assembly 6 includes an air filtration box 61, an inclined filter plate 62 is fixedly connected to the top of the air filtration box 61, an air filtration plate 63 is fixedly connected to the inner wall of the air filtration box 61, air filtration holes 64 are uniformly opened on the top of the air filtration plate 63, silica gel desiccant is filled between the air filtration plate 63 and the inclined filter plate 62, a rotating shaft 66 is uniformly penetrated and rotatably connected to the top of the air filtration plate 63, an arc-shaped transmission blade 67 is fixedly connected to the bottom side of the rotating shaft 66, a stirring rod 65 is uniformly fixedly connected to the part of the rotating shaft 66 above the air filtration plate 63, the bottom of the air filtration box 61 is open, the air filtration box 61 penetrates the top of the battery swapping cabinet 1 and is fixedly connected to the battery swapping cabinet 1.

[0026] In use, when the air cooler 52 is working, external air enters the battery swapping cabinet 1 through the opening at the bottom of the filter box 61. It first undergoes preliminary filtration by the inclined filter plate 62, which intercepts dust and other impurities. The intercepted dust and impurities slide off the inclined filter plate 62 to the outside of the battery swapping cabinet 1, preventing clogging of the filter structure. The filtered air then enters between the inclined filter plate 62 and the filter plate 63, where it comes into contact with the silica gel desiccant. The silica gel desiccant absorbs moisture from the air, drying it and preventing humid air from entering the battery swapping cabinet 1 and damaging components such as batteries. The air flow drives the arc-shaped drive blade 67 to rotate, which in turn drives the rotating shaft 66 to rotate. The stirring rod 65 on the rotating shaft 66 also rotates, causing the silica gel desiccant to agitate, ensuring full contact between the silica gel desiccant and the air, improving the drying effect, and providing a clean and dry air environment for the charging compartment 4. This is beneficial for battery charging and storage, extending battery life.

[0027] For the fourth embodiment, please refer to [link / reference]. Figures 1-11 Based on the third embodiment, the present invention provides a technical solution: the charging mechanism 7 includes a connecting frame 71, a fixed rod 72 is fixedly connected to the inner wall of the connecting frame 71, a rotating rod 73 is sleeved on the fixed rod 72 and rotatably connected to it, a first U-shaped frame 74 and a second U-shaped frame 75 are rotatably connected to both ends of the rotating rod 73 respectively, a second spring 76 is fixedly connected to the bottom end of the rotating rod 73 near the first U-shaped frame 74, an actuating rod 77 is fixedly connected to the side of the first U-shaped frame 74 away from the rotating rod 73, a sliding rod 78 is fixedly connected to the side of the second U-shaped frame 75 away from the rotating rod 73, a charging head 79 is fixedly connected to the end of the sliding rod 78 away from the second U-shaped frame 75, the connecting frame 71 is fixedly connected to one side of the charging compartment 4, the end of the second spring 76 away from the rotating rod 73 is fixedly connected to one side of the charging compartment 4, and both the actuating rod 77 and the sliding rod 78 pass through one side of the charging compartment 4 and are slidably connected to the charging compartment 4.

[0028] In use, when the battery to be charged is placed in the charging compartment 4, the battery is first guided and positioned by the elastic guide plate 89 and slides down between the first heat-conducting plate 81 and the second heat-conducting plate 83. When the battery is completely in contact with one side of the inner wall of the charging compartment 4, the battery will squeeze the trigger rod 77. After being squeezed, the trigger rod 77 pushes the first U-shaped frame 74 and the rotating rod 73 to rotate around the fixed rod 72. Under the action of the lever principle, the second U-shaped frame 75 will drive the sliding rod 78 and the charging head 79 to move towards the battery until the charging head 79 is tightly inserted into the charging interface of the battery, realizing automatic charging connection. When charging is complete and the battery needs to be removed, simply pull the battery outward. The pressure of the battery on the trigger rod 77 will disappear. Under the action of the elastic restoring force of the second spring 76, the rotating rod 73 will rotate in the opposite direction, driving the first U-shaped frame 74, the second U-shaped frame 75, the sliding rod 78 and the charging head 79 to reset. The charging head 79 will separate from the charging interface of the battery, and the battery can be easily removed, improving the convenience and automation of charging and avoiding missed charging.

[0029] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them.
