Description

[0001] This application claims priority to Chinese Patent Application No. 202411383873.5, filed on September 30, 2024, entitled "Power Adapter and Charging System", the entire contents of which are incorporated herein by reference. Technical Field

[0003] In recent years, with the continuous development of new energy technologies, various electric products have developed rapidly, such as power tools and electric vehicles, bringing great convenience to people's lives.

[0004] In some electric products, the battery pack is detachably connected to the main body. Once the battery pack's power is depleted, it can be replaced with a fully charged one, thus extending the product's operating time. The removed battery pack is typically installed in a charging dock for recharging.

[0005] In the prior art, when the battery pack is removed from the charging dock, the electrical connection points of the charging dock and the charging contacts of the battery pack are still electrically connected. Forcibly removing the battery pack from the charging dock will cause friction and sparks between the electrical connection points of the charging dock and the battery pack, which poses a significant safety hazard.

[0085] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0086] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0087] refer to Figures 1 to 23 This application provides a charging stand 100, which includes a charging stand body 10. The charging stand body 10 has a wall-mounting surface 11 and a battery mounting surface 12, the wall-mounting surface 11 and the battery mounting surface 12 being disposed opposite to each other. The battery mounting surface 12 has at least one battery mounting position 121 at a predetermined position, the battery mounting position 121 being used to mount a battery pack 200. The charging stand body 10 also has a first airflow opening 131 and a second airflow opening 132, the first airflow opening 131 being located at the battery mounting position 121.

[0088] refer to Figure 24 and Figure 25In some embodiments, the number of battery mounting positions 121 on the battery mounting surface 12 is one, capable of charging one battery pack at a time. (See reference) Figures 1 to 3 In some embodiments, the battery mounting surface 12 has two battery mounting positions 121 arranged side by side, capable of charging two battery packs at a time. In some embodiments, the number of battery mounting positions 121 may also be three or more. It is understood that the specific number of battery mounting positions 121 can be adjusted according to usage needs, and the specific number of battery mounting positions 121 should not constitute a limitation of this application.

[0089] During use, the charging base body 10 is suitable for hanging on a wall. When hung on a wall, the surface of the charging base body 10 facing the wall is the wall-mounting surface 11, and the surface away from the wall is the battery mounting surface 12. All other surfaces of the charging base body 10 are defined as sides. It should be noted that the specific way the charging base body 10 is used should not constitute a limitation of this application. For example, when charging the battery pack, the charging base body 10 can be hung on the vehicle body, carried on the back of a person, or placed on the ground.

[0090] refer to Figure 5 , Figure 6a and Figure 6b The charging base body 10 further includes a cooling fan 20, which is mounted on the charging base body 10. Preferably, the cooling fan 20 is a vortex fan (also referred to as a centrifugal fan). The cooling fan 20 has a heat dissipation housing 24 and an impeller 22 rotatably mounted on the heat dissipation housing 24. Specifically, the heat dissipation housing 24 forms a heat dissipation cavity 21, and the impeller 22 is rotatably mounted within the heat dissipation cavity 21. The cooling fan 20 also has an air inlet channel 231 arranged along the axial direction of the impeller 22 and an air outlet channel 232 arranged perpendicular to the axial direction of the impeller 22. The air inlet channel 231 faces the first airflow opening 131, and the air outlet channel 232 communicates with the second airflow opening 132. Both the air inlet channel 231 and the air outlet channel 232 communicate with the heat dissipation cavity 21. Preferably, the air outlet channel 232 faces the second airflow opening 132.

[0091] When the cooling fan 20 is operating, it can draw gas outside the first airflow opening 131 into the heat dissipation cavity 21 through the air inlet channel 231, and discharge it outside the second airflow opening 132 through the air outlet channel 232. Since the first airflow opening 131 is located at the battery mounting position 121, when the battery pack is installed in the battery mounting position 121 for charging, the cooling fan 20 can draw away the air around the battery pack, accelerate the airflow around the battery pack, and thus help dissipate heat from the battery pack.

[0092] It should be noted that the cooling fan 20 used in this application adopts an axial air intake and a perpendicular axial air exhaust method. The cooling fan 20 occupies a small space in the axial direction, which helps to reduce the thickness of the charging base body 10.

[0093] Preferably, the second airflow opening 132 is located on the side of the charging base body 10, allowing the gas discharged from the air outlet channel 232 to be discharged to one side of the battery pack. For example, the outline of the charging base body 10 is approximately square, and the second airflow opening 132 can be located on the top or bottom side of the charging base body 10, or on the left or right side. In some modified embodiments, the second airflow opening 132 can also be located on the wall-mounting surface 11. In some embodiments, the second airflow opening 132 can also be located in an area of ​​the battery mounting surface 12 where the battery mounting position 121 is not provided.

[0094] refer to Figure 5 , Figure 6a and Figure 6b Specifically, the charging dock 100 further includes a mounting housing 14, which has an installation space 140. The heat dissipation housing 24 is installed in the installation space 140, and the mounting housing 14 is installed on the charging dock body 10. In this application, the cooling fan 20 adopts a modular design. Before being installed on the charging dock body 10, the impeller, the heat dissipation housing 24, and the mounting housing 14 are assembled into a module and then assembled as a whole at a preset position on the charging dock body 10. In some modified embodiments, the heat dissipation cavity 21 can also be formed by a portion of the structure of the charging dock body 10, that is, the impeller is directly installed on the charging dock body 10.

[0095] refer to Figure 6aThe cooling fan 20 further includes a drive motor 25, which is mounted on the heat sink housing 24 and connected to the impeller 22, for driving the impeller 22 to rotate relative to the heat sink housing 24. The impeller 22 includes a plurality of fan blades 221 arranged around the drive motor 25, forming a partial air intake channel 231 between the plurality of fan blades 221 and the drive motor 25, with a predetermined gap between adjacent fan blades 221. The cooling fan 20 further includes a baffle 251, which is disposed on the side of the drive motor 25 away from the first airflow opening 131, and connects the drive motor 25 and the plurality of fan blades 221. During operation of the cooling fan 20, the drive motor 25 drives the plurality of fan blades 221 to rotate, and the gas in the internal space formed around the impeller 22 is thrown out to the outside of the impeller 22 through the gaps between the fan blades 221, creating a negative pressure within the internal space formed around the impeller 22, continuously drawing in external gas.

[0096] Preferably, the drive motor 25 is an external rotor motor.

[0097] Specifically, the heat dissipation housing 24 has a heat dissipation housing body 241 and an extension 242 extending outward from the heat dissipation housing body 241 perpendicular to the axial direction of the impeller 22. The impeller 22 is rotatably mounted on the heat dissipation housing body 241. The heat dissipation housing body 241 surrounds to form the heat dissipation cavity 21, and the extension 242 surrounds to form the air outlet channel 232. The mounting housing 14 includes a mounting housing body 141 and a limiting plate 142. The connecting end 1421 of the limiting plate 142 is mounted on the first side wall 1411 of the mounting housing body 141, and a limiting opening 1420 is provided between the limiting end 1422 of the limiting plate 142 and the second side wall 1412 of the mounting housing body 141. The first side wall 1411 and the second side wall 1412 are disposed opposite to each other. The mounting housing body 141 and the limiting plate 142 surround to form the mounting space 140, and the limiting opening 1420 communicates with the mounting space 140. The distal surface 2421 of the extension 242 is attached to the second sidewall 1412, and the limiting end 1422 of the limiting plate 142 abuts against the proximal surface 2422 of the extension 242.

[0098] The heat sink body 241 has a roughly circular outline in the top view. The distal surface 2421 is approximately tangent to the edge of the extension 242, and the distance between it and the impeller shaft is slightly greater than the radius of the impeller. This surface of the extension 242 is defined as the distal surface 2421. The proximal surface 2422 is positioned opposite the distal surface 2421 and is closer to the impeller shaft than the distal surface 2421. This surface is defined as the proximal surface 2422. The distance between the distal surface 2421 and the proximal surface 2422 is less than the diameter of the heat sink body 241, and the connection between the proximal surface 2422 and the heat sink body 241 is a curved corner. The mounting space 140 formed by the mounting housing body 141 has a shape adapted to the heat dissipation housing 24. When the heat dissipation housing 24 is installed in the mounting space 140, one end of the extension body 242 away from the heat dissipation housing body 241 extends through the limiting opening 1420 to the outside of the limiting opening 1420. The limiting end 1422 of the limiting plate 142 abuts against the connection between the extension body 242 and the heat dissipation housing body 241, which can limit the heat dissipation housing 24 and improve the stability of the heat dissipation housing 24 when installed in the mounting space 140.

[0099] refer to Figure 6b Preferably, the axis of rotation of the impeller 22 is parallel and offset to the central axis of the heat sink body 241, that is, the plurality of fan blades 221 are distributed in a central circular array, the center of which is off-center from the center of the heat sink body 241. This is the direction from the near-axial surface 2422 to the far-axial surface 2421, or along the rotation direction of the impeller 22, or... Figure 6b In the direction of the middle arrow, the distance between the outer ring of the impeller 22 and the heat sink body 241 gradually increases, and the airflow thrown out from between the fan blades 221 flows through the gap between the outer ring of the impeller 22 and the heat sink body 241 to the air outlet channel 232.

[0100] Preferably, the air intake channel of the cooling fan 20 has a circular cross-section with a diameter of not less than 50 mm, for example, 60 mm; the air outlet channel has a rectangular cross-section with an area of ​​not less than 1000 mm². 2 For example, a length of 53mm, a height of 29mm, and an area of ​​1573mm². 2 Preferably, the rated speed of the cooling fan 20 is 4500 rpm.

[0101] Specifically, the mounting housing 14 further includes a first abutment plate 143 and a second abutment plate 144. One end of the first abutment plate 143 is connected to the limiting end 1422, and the other end extends to the end of the extension body 242 away from the heat dissipation shell body 241 and abuts against the extension body 242. One end of the second abutment plate 144 is connected to the second sidewall 1412, and the other end extends to the end of the extension body 242 away from the heat dissipation shell body 241 and abuts against the extension body 242. For example, the limiting plate 142 mainly limits the heat dissipation housing 24 in the direction perpendicular to the gas flow in the air outlet channel 232 within the extension body 242, and the first abutment plate 143 and the second abutment plate 144 mainly limit the heat dissipation housing 24 in the direction parallel to the gas flow in the air outlet channel 232 within the extension body 242.

[0102] Specifically, the outer peripheral surface of the heat sink body 241 has a plurality of first screw portions 2411 at a predetermined position. Screws are driven into the first screw portions 2411 to detachably install the heat sink body 241 onto the mounting housing 14. The outer peripheral surface of the mounting housing body 141 has a plurality of second screw portions 1413 at a predetermined position. Screws are driven into the second screw portions 1413 to detachably install the mounting housing 14 onto the charging base body 10.

[0103] refer to Figure 1 Furthermore, the battery mounting position 121 has a mounting boss 122 extending from the battery mounting surface 12 in a direction away from the wall mounting surface 11, and the first airflow opening 131 is located on the front side 1221 of the mounting boss 122 away from the wall mounting surface 11. The charging base body 10 has a high end portion 151 and a low end portion 152, and the charging base body 10 has an electrical connection terminal 16 corresponding to the position of the battery mounting position 121. The electrical connection terminal 16 is disposed on the top surface of the mounting boss 122 near the high end portion 151. When the battery pack is installed in the battery mounting position 121, the battery pack is slid along the mounting boss 122 from the high end portion 151 to the low end portion 152. When the battery pack slides to a preset position, the electrical connection terminal 16 can be electrically connected to the battery pack. In this application, the first airflow opening 131 is disposed on the front side 1221 of the mounting boss 122. When the battery pack is installed in the battery mounting position 121, the first airflow opening 131 is positioned directly facing the battery pack, which can improve heat dissipation efficiency.

[0104] refer to Figure 7Sliding grooves 1222 are respectively formed on both sides of the mounting boss 122. The sliding grooves 1222 extend along the height direction of the mounting boss 122 to allow the battery pack to slide along the mounting boss 122 from the high end portion 151 to the low end portion 152. The sliding grooves 1222 include a top sliding groove 1223 and a bottom sliding groove 1224 from top to bottom. The distance between the inner wall of the top sliding groove 1223 away from the wall surface 11 and the wall surface 11 is greater than the distance between the inner wall of the bottom sliding groove 1224 away from the wall surface 11 and the wall surface 11. In some embodiments, along a direction perpendicular to the wall surface 11, the groove width of the top sliding groove 1223 is greater than the groove width of the bottom sliding groove 1224. In some embodiments, along a direction perpendicular to the wall-mounting surface 11, the width of the top sliding groove 1223 is the same as the width of the bottom sliding groove 1224, but the center of the top sliding groove 1223 is further away from the wall-mounting surface 11 than the center of the bottom sliding groove 1224. A guiding ramp 1225 is provided at the connection between the inner walls of the top sliding groove 1223 and the bottom sliding groove 1224. As the battery pack moves from top to bottom along the sliding groove 1222 from the top sliding groove 1223 to the bottom sliding groove 1224, the distance between the battery pack and the battery mounting surface 12 decreases, allowing the battery pack to be closer to the battery mounting surface 12.

[0105] Specifically, the front side 1221 of the mounting boss 122 has a plurality of staggered reinforcing ribs 123, and an opening plate 124 is formed in the area between adjacent reinforcing ribs 123. The opening plate 124 has a plurality of first airflow openings 131. The surface of the opening plate 124 has a height difference from the surface of the reinforcing ribs 123, and the reinforcing ribs 123 form air guide grooves 1240 on the side of the opening plate 124 away from the cooling fan 20. When the battery pack is installed in the battery mounting position 121, the opening plate 124 is at a certain distance from the surface of the battery pack, thereby preventing the surface of the battery pack from blocking the first airflow openings 131.

[0106] There is a preset distance between the perforated plate 124 and the air inlet of the cooling fan 20, and an air guiding space 125 is formed between the perforated plate 124 and the cooling fan 20. Similarly, maintaining a certain distance between the cooling fan 20 and the perforated plate 124 can also prevent part of the structure of the cooling fan 20 from blocking the first airflow opening 131 on the perforated plate 124.

[0107] refer to Figure 1The battery mounting position 121, the first airflow opening 131, the second airflow opening 132, and the cooling fan 20 are all in pairs, with the two second airflow openings 132 located on opposite sides of the charging base body 10. In some modified embodiments, the two air outlet channels 232 can be converged at the middle position of the two cooling fans 20 and then discharged through one of the second airflow openings 132.

[0108] refer to Figure 24 The charging base body 10 also has a third airflow opening 133 formed on the wall mounting surface 11. The third airflow opening 133 is connected to the air outlet channel 232 so that the gas discharged by the cooling fan 20 can be discharged from the wall mounting surface 11 through the third airflow opening 133.

[0109] refer to Figure 11 Furthermore, the charging base body 10 has a movable groove 171 corresponding to the battery mounting position 121, and the battery mounting position 121 has a locking opening 172, which communicates with the movable groove 171.

[0110] The charging dock 100 further includes a first locking mechanism 30, which includes a movable latch 31. The movable latch 31 is movably mounted on the charging dock body 10. The movable latch 31 has a first state and a second state. In the first state and the second state, the movable latch 31 has different positions relative to the charging dock body 10.

[0111] Preferably, the movable end 311 of the movable latch 31 is slidably mounted in the movable slot 171. In the first state, the locking end 312 of the movable latch 31 extends from the battery mounting position 121 and is adapted to extend into the locking slot 201 of the battery pack 200. In the second state, the locking end 312 retracts towards the charging base body 10 and is adapted to leave the locking slot 201. When the movable latch 31 is in the first state, the locking end 312 can lock and limit the battery pack, improving the stability of the battery pack when installed in the battery mounting position 121. When the movable latch 31 is in the second state, the locking end 312 leaves the battery pack, making it easier to remove the battery pack from the battery mounting position 121.

[0112] The charging dock 100 further includes a status monitoring mechanism 40, which is disposed on the movement path of the movable block 31 and is used to monitor the status of the movable block 31. In the first state, the electrical connection terminal 16 is electrically connected to an external power source; in the second state, the electrical connection between the electrical connection terminal 16 and the external power source is disconnected.

[0113] Before connecting the electrical connection terminal 16 to the charging port 202 of the battery pack 200 and / or before separating the electrical connection terminal 16 from the charging port 202, the movable latch 31 is adapted to be adjusted to the second state; when the electrical connection terminal 16 is connected to the charging port 202, the movable latch 31 is adapted to be adjusted to the first state. The charging socket 100 can disconnect the electrical connection terminal 16 from the outside during the insertion and removal of the battery pack 200, thereby avoiding the generation of electrical sparks during the insertion and removal of the battery pack 200.

[0114] The charging dock 100 has three states: no package inserted, fully inserted, and in the process of inserting a package. (Reference) Figure 19 The charging dock 100 is in the unpacked insertion state. (Reference) Figure 20 The charging dock 100 is in the fully inserted state. (Reference) Figure 21 The charging dock 100 is in the insertion process state. In both the uninserted state and the fully inserted state, the movable latch 31 is in the first state; in the insertion process state, the battery pack 200 abuts against the locking end 312 of the movable latch 31, pushing the locking end 312 a preset distance toward the charging dock body 10, and the movable latch 31 is in the second state.

[0115] The status monitoring mechanism 40 includes a first contact and a second contact. In the first state, the first contact and the second contact are separated from each other. In the second state, the first contact and the second contact are in contact with each other. When the first contact and the second contact are in contact with each other, the electrical connection between the electrical connection terminal 16 and the external power supply is disconnected.

[0116] refer to Figure 11 and Figure 12The status monitoring mechanism 40 further includes a monitoring switch 45 and an elastic arm 453. The monitoring switch 45 includes a base 451 and an active button 452. The active button 452 is telescopically mounted on the base 451. One end of the elastic arm 453 is rotatably mounted on the base 451, and the other end of the elastic arm 453 extends into the movement path of the active block 31. The active button 452 is located between the elastic arm 453 and the base 451. The first contact 41 is disposed on the active button 452, and the second contact 453 is disposed on the base 451. In the second state, the movable block 31 pushes the other end of the elastic arm 453 toward the base 451 and squeezes the active button 452 into the base 451, causing the first contact 451 and the second contact 452 to contact. In the first state, the movable block 31 separates from the other end of the elastic arm 453, increasing the distance between the other end of the elastic arm 453 and the base 451, causing the active button 452 to move away from the base 451, and the first contact 41 and the second contact 452 to separate. Preferably, a spring is also disposed between the active button 452 and the base 451, so that when the distance between the elastic arm 453 and the base 451 increases, the spring can push the active button 452 away from the base 451.

[0117] Furthermore, the movable block 31 has a push arm 314 on its side. When the movable block 31 moves, the push arm 314 can contact the elastic arm 453 and push the elastic arm 453 to squeeze the pressure sensor 452.

[0118] The end of the push arm 314 away from the monitoring base 451 has an arc-shaped protrusion 4531. The arc-shaped protrusion 4531 can increase the stroke of the elastic arm 453 when it is pushed by the push arm 314, thereby increasing the pressure on the active button 452.

[0119] In some modified embodiments, the state monitoring mechanism 40 includes a monitoring base, a pressure sensor, and the elastic arm. One end of the elastic arm 453 is rotatably mounted on the monitoring base. The pressure sensor is disposed on the monitoring base, and the detection end of the pressure sensor faces the elastic arm 453. During the process of the movable block 31 switching from the first state to the second state, the movable block 31 can push the elastic arm 453 to squeeze the pressure sensor, and the state of the movable block is determined based on the pressure value of the pressure sensor.

[0120] In some modified embodiments, the state monitoring mechanism 40 includes a proximity switch. In one example, the proximity switch is a Hall effect proximity switch. A magnetic element is disposed at a preset position on the movable block 31, and a Hall effect element is disposed at a preset position on the charging base body 10. When the position of the movable block 31 relative to the charging base body 10 changes, the position of the magnetic element relative to the Hall effect element changes, causing a change in the internal circuit state of the switch due to the Hall effect. The state of the movable block 31 is determined, thereby controlling the connection or disconnection between the electrical connection terminal 16 and the external circuit.

[0121] In one example, the proximity switch is a photoelectric proximity switch. A reflective element is set at a preset position of the movable block 31, and a light-emitting device and a photoelectric device are set at a preset position of the charging base body 10. When the position of the movable block 31 relative to the charging base body 10 changes, the reflected light received by the photoelectric device will also change, thereby determining the state of the movable block 31 and controlling the connection between the electrical connection terminal 16 and the external circuit.

[0122] In one example, the proximity switch is a capacitive proximity switch. The measuring head of the capacitive proximity switch and the area of ​​the charging base body 10 corresponding to the movable block 31 form the two plates of a capacitor. When the position of the movable block 31 relative to the charging base body 10 changes, it will cause a change in the capacitance of the capacitor. The state of the movable block 31 is thus determined, thereby controlling the connection between the electrical connection terminal 16 and the external circuit.

[0123] refer to Figure 18In some modified embodiments, the first contact 41 is disposed on the inner surface of the movable groove 171, and the second contact 42 is disposed on the movable end 311. In the first state, the first contact 41 and the second contact 42 are in contact, and the electrical connection terminal 16 is electrically connected to an external power source; in the second state, the first contact 41 and the second contact 42 are separated, and the electrical connection between the electrical connection terminal 16 and the external power source is disconnected. In this application, during the process of the movable block 31 switching from the first state to the second state, the first contact 41 and the second contact 42 are separated, and the electrical connection between the electrical connection terminal 16 and the external power source is disconnected. This can prevent electrical sparks from being generated when the battery pack is separated from the electrical connection terminal 16 when the battery pack is removed from the battery mounting position 121 in a power-off state, thereby improving the safety during charging. Further, the status monitoring mechanism 40 further includes a monitoring power supply 43, the positive terminal of which is electrically connected to the first contact 41, and the negative terminal is electrically connected to the second contact 42. When the first contact 41 and the second contact 42 are in contact, the positive and negative terminals of the monitoring power supply 43 are connected. When the first contact 41 and the second contact 42 are separated, the connection between the positive and negative terminals of the monitoring power supply 43 is broken. The status monitoring mechanism 40 further includes a galvanometer 44, which is disposed on the connection circuit between the positive terminal of the monitoring power supply 43 and the first contact 41 or on the connection circuit between the negative terminal of the monitoring power supply 43 and the second contact 42. The galvanometer 44 is used to detect whether current flows through the circuit. When the first contact 41 and the second contact 42 are in contact, the galvanometer 44 can detect current. When the first contact 41 and the second contact 42 are separated, the galvanometer 44 cannot detect current.

[0124] The charging dock 100 further includes a control board 51 and an external wiring 52. The control board 51 is installed in a preset position within the charging dock body 10. One end of the external wiring 52 is electrically connected to the control board 51, and the other end is adapted to be electrically connected to an external power source. The control board 51 is also electrically connected to the electrical connection terminal 16. The control board 51 can control the electrical connection state between the external wiring 52 and the electrical connection terminal 16. For example, the control board 51 can electrically connect or disconnect the external wiring 52 from the electrical connection terminal 16. The end of the external wiring 52 away from the control board 51 can be directly connected to an external socket for power, or it can be first connected to a charger and then connected to an external socket for power.

[0125] In some embodiments, the charging base body 10 further includes a housing space for accommodating the mounting housing 14, the control board 51 is mounted in the housing space, and the control board 51 is electrically connected to the electrical connection terminal 16. The housing space is connected to the second airflow opening 132 and / or the third airflow opening 133, so that the heat generated by the control board 51 during operation can be guided to the outside of the second airflow opening 132 and / or the third airflow opening 133 by the airflow. It should be noted that although the air outlet channel 232 does not flow directly through the control board 51, the air pressure in the air outlet channel 232 is greater than the standard atmospheric pressure, so that the gas in the air outlet channel 232 can be discharged through the second airflow opening 132 and / or the third airflow opening 133. During this process, the airflow disturbance causes the air around the control board 51 to flow, thereby generating a certain heat dissipation effect on the control board 51.

[0126] The control board 51 is also connected to the ammeter 44. When the ammeter 44 detects current, the control board 51 controls the external wiring 52 to be electrically connected to the electrical connection terminal 16. When the ammeter 44 does not detect current, the control board 51 controls the electrical connection between the external wiring 52 and the electrical connection terminal 16 to be disconnected.

[0127] refer to Figure 11 and Figure 12 Furthermore, the first locking mechanism 30 further includes an elastic element 32, which is installed in the movable groove 171. One end of the elastic element 32 is connected to the movable end 311, and the other end is connected to the inner wall of the movable groove 171. When the movable block 31 switches from the first state to the second state, the elastic element 32 undergoes a preset deformation. After the external force acting on the movable block 31 disappears, the elastic element 32 returns to its original state, causing the movable block 31 to switch from the second state to the first state.

[0128] Specifically, when the movable block 31 switches from the first state to the second state, the elastic element 32 is compressed. After the external force acting on the movable block 31 disappears, the elastic element 32 returns to its original length, causing the movable block 31 to switch from the second state to the first state. For example, when the movable block 31 is in the first state, the elastic element 32 is in its natural state. When the movable block 31 is in the second state, the elastic element 32 is compressed. After the external force acting on the movable block 31 disappears, the elastic element 32 pushes the movable block 31 back from the second state to the first state as it returns to its natural state from the compressed state.

[0129] refer to Figure 12 Furthermore, the movable locking block 31 has a first limiting post 3111 extending from the movable end 311 in a direction away from the locking end 312. (See reference) Figure 11 The movable groove 171 has a second limiting post 3112 extending towards the locking opening 172 on its inner wall away from the locking opening 172. The first limiting post 3111 and the second limiting post 3112 are coaxially arranged. The elastic element 32 is a spring, with one end of the spring sleeved on the first limiting post 3111 and the other end sleeved on the second limiting post 3112. In other words, the first limiting post 3111 and the second limiting post 3112 extend into the internal space of the spring by a predetermined distance, which can limit the two ends of the spring and improve the stability of the connection between the two ends of the elastic element 32 and the movable end 311 and the inner wall of the movable groove 171.

[0130] Furthermore, in the direction of movement perpendicular to the movable locking block 31, the depth of the movable groove 171 is greater than the width of the locking opening 172, and the portion of the sidewall of the movable groove 171 surrounding the locking opening 172 forms a first abutment portion 1711. In the direction of movement perpendicular to the movable locking block, the thickness of the movable end 311 is greater than the thickness of the locking end 312, and the portion of the movable end 311 extending beyond the locking end 312 forms a second abutment portion 1712. In the first state, the first abutment portion 1711 abuts against the second abutment portion 1712; in the second state, the first abutment portion 1711 and the second abutment portion 1712 are separated. In the first state, the first abutment portion 1711 abuts against the second abutment portion 1712, meaning that the inner wall of the movable groove 171 can limit the movement of the movable locking block 31, controlling the length by which the locking end 312 of the movable locking block 31 extends beyond the locking opening 172.

[0131] Specifically, the first contact 41 is located at the first abutment portion 1711, and the second contact 42 is located at the second abutment portion 1712.

[0132] refer to Figure 11Furthermore, the outer surface of the locking end 312 away from the movable end 311 is a guide surface 3121, and the distance between the top of the guide surface 3121 and the movable end 311 is less than the distance between the bottom of the guide surface 3121 and the movable end 311. Preferably, the guide surface 3121 is a sloped or arc-shaped surface. During the movement of the battery pack 200 along the mounting boss 122 from the high end portion 151 to the low end portion 152, the preset position of the battery pack 200 can contact the guide surface 3121, and during the downward movement, it pushes the movable latch 31 to switch from the first state to the second state. After the battery pack 200 is fully installed, the movable latch 31 switches from the second state to the first state. Preferably, the first state is a locked state, and the second state is an unlocked state.

[0133] refer to Figure 11 and Figure 12 Furthermore, the first locking mechanism 30 further includes an unlocking member 33. The charging base body 10 has an unlocking opening 173 communicating with the movable groove 171. The inner end portion 331 of the unlocking member 33 is located in the movable groove 171 and is connected to the movable block 31. The outer end portion 332 of the unlocking member 33 extends through the unlocking opening 173 to the outside of the movable groove 171. Moving the outer end portion of the unlocking member 33 along a preset path relative to the charging base body 10 can drive the movable block 31 to move within the movable groove 171 and switch from the first state to the second state.

[0134] Preferably, the unlocking member 33 is rotatably mounted on the charging dock body 10. In some embodiments, the unlocking member 33 can also be mounted on the charging dock body 10 in a manner that allows it to slide relative to the charging dock body 10. Taking the unlocking member 33 being rotatably mounted on the charging dock body 10 as an example, the unlocking member 33 further has a middle portion 333 located between the inner end portion 331 and the outer end portion 332, and two rotating posts 3331 extend outward from both sides of the middle portion 333. The inner wall of the movable groove 171 has two corresponding rotating grooves 1713, and the two rotating posts 3331 are rotatably mounted in the two rotating grooves 1713 respectively. For example, during use, when the outer end 332 of the unlocking member 33 is moved toward the direction of the battery mounting surface 12, the rotating column 3331 rotates in the rotating groove 1713, and the inner end 331 of the unlocking member 33 can move toward the direction of the wall-mounting surface 11. The inner end 331 drives the movable block 31 to move toward the direction of the wall-mounting surface 11, and switches from the first state to the second state.

[0135] Furthermore, the outer end portion 332 of the unlocking member 33 has an operating groove 3321. When the outer end portion 332 of the unlocking member 33 is moved, the operating groove 3321 is adapted to accommodate the operator's finger so that the operator can move the unlocking member 33.

[0136] Furthermore, the top of the movable locking block 31 has an insertion slot 313, and the inner end portion 331 of the unlocking member 33 is inserted into the insertion slot 313. The inner end portion 331 has an abutment post 3311, which is rotatably mounted in the insertion slot 313. When the outer end portion 332 of the unlocking member 33 is moved to rotate the inner end portion 331, the abutment post 3311 can rotate relative to the inner wall of the insertion slot 313.

[0137] The outer end portion 332 of the unlocking member 33 has a first arc-shaped partition 334 on the side near the battery mounting position 121, and a second arc-shaped partition 335 on the side away from the battery mounting position 121. It should be noted that in the first state, there is a first gap between the outer end portion 332 of the unlocking member 33 and the side wall of the unlocking opening 173 near the battery mounting surface 12. One end of the first arc-shaped partition 334 is connected to a preset position of the outer end portion 332, and the other end extends towards the battery mounting surface 12 with a preset arc, thereby partially concealing the first gap. In the second state, there is a second gap between the outer end portion 332 of the unlocking member 33 and the side wall of the unlocking opening 173 near the wall mounting surface 11. One end of the second arc-shaped partition 335 is connected to a preset position of the outer end portion 332, and the other end extends towards the wall mounting surface 11 with a preset arc, thereby partially concealing the second gap.

[0138] The inner wall of the movable slot 171 near the wall mounting surface 11 has an abutment plate 1714 extending a predetermined length toward the battery mounting surface. When the movable latch 31 is in the first state, the bottom of the second arc-shaped partition 335 abuts against the abutment plate 1714. When the movable latch 31 is in the second state, there is a certain distance between the bottom of the second arc-shaped partition 335 and the abutment plate 1714.

[0139] An anti-deviation groove 1715 is provided in the middle of the abutment plate 1714. The unlocking member 33, located near the abutment plate 1714 and below the first arc-shaped partition 334, has an anti-deviation plate 336 extending towards the abutment plate 1714. The anti-deviation plate 336 is slidably installed within the anti-deviation groove 1715 and can limit the unlocking member 33 when it rotates relative to the inner wall of the movable groove 171, causing the unlocking member 33 to rotate along a preset trajectory. The charging base body 10 has a movable housing 17, which surrounds and forms the movable groove 171.

[0140] refer to Figure 1 Furthermore, the charging dock 100 further includes a bottom support plate 60 extending from the lower end portion 152 of the charging dock body 10 toward the wall mounting surface 11 away from the charging dock body 10. When the battery pack is installed in the battery mounting position 121, the bottom support plate 60 can provide support for the bottom of the battery pack.

[0141] The bottom support plate 60 has a locking groove 61 and a locking opening 62 communicating with the locking groove 61 at the position corresponding to the battery mounting position 121. The charging base 100 further includes a second locking mechanism 70, which includes a rotating arm 71. The rotating arm 71 is rotatably mounted on the inner wall of the locking groove 61, and the locking end 711 of the rotating arm 71 extends through the locking opening 62 to the side of the bottom support plate 60 facing the battery mounting position 121.

[0142] The second locking mechanism 70 further includes a second elastic element 72, which is disposed between the bottom of the locking end 711 and the inner wall of the locking groove 61. Preferably, the second elastic element 72 is a spring. The rotating arm 71 has a first state and a second state. In the first state, the locking end 711 of the rotating arm 71 extends out of the locking opening 62, and the top of the rotating arm 71 abuts against the top surface of the locking groove 61. In the second state, the locking end 711 of the rotating arm 71 is rotated by a predetermined angle towards the bottom of the locking groove 61 under the pressure of the battery pack. There is a certain gap between the rotating arm 71 and the top surface of the locking groove 61. The second elastic element 72 is compressed, and the second elastic element 72 can provide a counterforce to the rotating arm 71 so that the locking end 711 can be fully engaged with the battery pack. After the battery pack is removed from the battery mounting position 121, the second elastic member 72 can push the rotating arm 71 to rotate, causing the locking end 711 to extend out of the locking opening 62.

[0143] refer to Figure 1 Furthermore, a handle 18 is provided on the high end portion 151 of the charging dock body 10 for the operator to hold, so as to facilitate the operator to move the charging dock.

[0144] refer to Figure 26 , Figure 27 as well as Figure 28 According to another aspect of this application, a ride-on lawnmower 300 is further provided, the ride-on lawnmower 300 including a lawnmower body 301, the movable latch 31, and the status monitoring mechanism 40. The lawnmower body 301 has at least one battery mounting position 121 for mounting the battery pack 200; the lawnmower body 301 has an electrical connection terminal 16 corresponding to the position of the battery mounting position 121. The movable latch 31 is movably mounted on the lawnmower body 301, and the movable latch 31 has a first state and a second state, in which the movable latch 31 has different positions relative to the lawnmower body 301.
