Description

Technical Field

[0001] The present application relates to the technical field of charging stacks, and in particular to a waterproof device for charging equipment and a charging device. Background Art

[0002] With the continuous development of the new energy vehicle industry, charging equipment for new energy vehicles has also made significant progress. To overcome the problems of fixed output power, limited compatibility, and low utilization of traditional charging piles, charging stack technology has emerged. Using a matrix topology, charging stacks dynamically aggregate power modules across piles, enabling dynamic charging of multiple vehicles. This significantly improves power supply capacity utilization and avoids wasted power resources.

[0003] However, the design of most charging guns may not fully address the need for waterproofing and dustproofing, making it easy for rainwater to enter the gun when used on rainy days. Furthermore, in extreme weather conditions such as strong winds and heavy rain, rainwater can enter the gun through various gaps. Due to the strong conductivity of water, water intrusion can cause electrical shorts, resulting in equipment damage or even fire. Furthermore, moisture can corrode the metal components within the gun, affecting charging performance and device lifespan. Furthermore, electric vehicle users may experience electric shock when using a flooded gun, posing a safety hazard. Summary of the Invention

[0004] Based on this, it is necessary to provide a waterproof device and charging equipment to address the problem that rainwater can easily enter the interior of the charging gun, causing equipment damage or even fire, affecting charging performance and equipment life, and posing safety hazards.

[0011] In one embodiment, the waterproof device of the charging device also includes a closing mechanism, which is located between the first water removal mechanism and the second water removal mechanism along the depth direction of the charging socket. The closing mechanism is linked to the first water absorbing member to open or close the part of the charging socket connected to the first water removal mechanism and the second water removal mechanism when the first water absorbing member rotates.

One end of the pull cord is connected to the folding door, and the other end passes around the roller and is connected to the rotating shaft of a corresponding first water absorbent member.

[0013] When the charging gun is inserted into the charging socket and the first water absorbent part rotates, the pull rope can be wrapped around the rotating shaft of the first water absorbent part and contracted, so that the folding door is elastically compressed and folded; when the charging gun is pulled out of the charging socket and the first water absorbent part rotates, the pull rope can be untied from the rotating shaft of the first water absorbent part and stretched, so that the folding door opens under the action of elastic restoring force.

[0043] See Figures 1 to 5A waterproof device 100 for charging equipment provided in one embodiment of the present application is applied to a charging device 200. The charging device 200 is a device capable of charging an external structure, and can specifically be a charging pile or a charging stack. The charging device 200 includes a charging body 210 and a charging gun 220. The charging body 210 has a charging socket 2101. The charging gun 220 can be inserted into or removed from the charging socket 2101. The waterproof device 100 for charging equipment is disposed in the charging socket 2101. It will be understood that when the charging gun 220 is removed from the charging socket 2101, the charging gun 220 can be docked with an external structure, such as an electric vehicle, to charge the electric vehicle. When the charging gun 220 is inserted into the charging socket 2101, the charging gun 220 can be stored and protected from damage.

[0044] See Figure 6 and Figure 7 The charging device waterproof device 100 of the embodiment of the present application is arranged in the charging socket 2101, and specifically includes a first water removal mechanism 10 and a second water removal mechanism 20.

[0045] The first water removal mechanism 10 includes two first water removal components 11, which are arranged opposite to each other along the width direction of the charging socket 2101 to form a propulsion channel AA. When the charging gun 220 is inserted into or removed from the charging socket 2101, it can enter or retreat from the propulsion channel AA to remove water from at least the side wall of the charging gun 220 through the first water removal component 11.

[0046] The width direction of the charging socket 2101 referred to here is as follows Figure 4 The direction perpendicular to the paper surface shown can also be understood as the horizontal direction. When the charging socket 2101 is a circular socket, the width direction of the charging socket 2101 is equivalent to the radial direction of the charging socket 2101 parallel to the horizontal direction.

[0047] The direction in which the charging gun 220 is inserted into or removed from the charging socket 2101 is actually the depth direction of the charging socket 2101. Figure 4 Horizontal direction shown.

[0048] When the charging gun 220 is inserted into the charging socket 2101 and enters the propulsion channel AA along the charging socket 2101, the first water removal assemblies 11 on both sides of the charging gun 220 can remove water from the side walls of the charging socket 2101. Similarly, when the charging gun 220 is removed from the charging socket 2101 and withdraws from the propulsion channel AA along the charging socket 2101, the first water removal assemblies 11 on both sides of the charging gun 220 can also remove water from the side walls of the charging socket 2101. The water removal methods of the first water removal assemblies 11 are not limited to wiping, suctioning, scraping, blowing, etc.

[0049] The second water removal mechanism 20 is located inside the first water removal mechanism 10 along the depth direction of the charging socket 2101 . The second water removal mechanism 20 can contact the end surface of the charging gun 220 to remove water from the end surface of the charging gun 220 .

[0050] The second water removal mechanism 20 is located inside the first water removal mechanism 10 along the depth direction of the charging socket 2101 , which means that along the depth direction of the charging socket 2101 , the second water removal mechanism 20 is deeper in the charging socket 2101 than the first water removal mechanism 10 .

[0051] The end face of the charging gun 220 refers to the surface where the charging port 2201 of the charging gun 220 is located. When the charging gun 220 is inserted into the charging socket 2101 and enters the propulsion channel AA along the charging socket 2101, and contacts the second water removal mechanism 20, the end face of the charging gun 220 can be dewatered. The dewatering method of the second dewatering mechanism 20 is not limited to wiping, suction, scraping, blowing, etc. The dewatering method of the second dewatering mechanism 20 can be the same as the dewatering method of the first dewatering component 11, for example, both are suction removal, or it can be different from the dewatering method of the first dewatering component 11.

[0052] The charging device waterproof device 100 of the embodiment of the present application is arranged in the charging socket 2101. Therefore, when the charging gun 220 is inserted into or unplugged from the charging socket 2101, water can be removed from the side walls of the charging gun 220 through the first water removal mechanism 10, and the end face of the charging gun 220 can be further removed through the second water removal mechanism 20. Therefore, water droplets, water stains, etc. on the surface of the charging gun 220 are reduced, thereby reducing the risk of water entering the interior of the charging gun 220, improving the charging performance and service life of the charging gun 220, and also improving the safety of the user when using the charging gun 220 for charging.

[0053] See Figures 5 to 9 Specifically in the embodiment of the present application, each first water removal assembly 11 includes a rotatable first water absorbing member 111. At least a portion of the propulsion channel AA is formed between the two first water absorbing members 111 of the two first water removal assemblies 11. When the charging gun 220 is inserted into or removed from the charging socket 2101, it can cooperate with each first water removal assembly 11 so that the corresponding first water absorbing member 111 rotates. When the charging gun 220 enters or exits the propulsion channel AA, it fits against each first water absorbing member 111 to remove water from the side wall of the charging gun 220.

[0054] That is, when the charging gun 220 is inserted into or removed from the charging socket 2101 , it can drive the first water removal assembly 11 to follow its movement, so that the first water absorbing member 111 rotates.

[0055] Because the first water absorbing member 111 rotates and adheres to the charging gun 220 during insertion or removal from the charging socket 2101, it effectively absorbs and removes water from the sidewalls of the charging gun 220. Compared to a stationary first water absorbing member 111, the rotating member more easily absorbs water into the first water absorbing member 111 and prevents water from accumulating on one side of the first water absorbing member 111, thereby improving water absorption reliability.

[0056] It should be noted that the first water absorbing member 111 rotates in the opposite direction when the charging gun 220 is inserted into or removed from the charging socket 2101. In other words, when the charging gun 220 is inserted into or removed from the charging socket 2101, it can cooperate with each first water removal assembly 11 to cause the corresponding first water absorbing member 111 to rotate forward or reverse.

[0057] Furthermore, the first water absorbing member 111 includes a rotatable shaft 1111 and a water absorbing sleeve 1112. The water absorbing sleeve 1112 is mounted on the shaft 1111 and is detachable relative to the shaft 1111. In this way, when the water absorbing sleeve 1112 needs to be replaced after long-term use, the staff can pull out the water absorbing sleeve 1112 and replace it with a clean and dry water absorbing sleeve 1112 in a timely manner, thereby ensuring the water absorption efficiency of the water absorbing sleeve 1112.

[0058] Specifically, the water absorption sleeve 1112 may be a sponge water absorption sleeve. In other embodiments, the water absorption sleeve 1112 may also be a water absorption sleeve made of other materials with adsorption properties.

[0059] Furthermore, a groove 1111a is provided on the outer wall of the shaft 1111, and the groove 1111a extends along the axial direction of the shaft 1111, and at least one end passes through the shaft 1111. A protrusion 1112a is provided on the inner wall of the water absorption sleeve 1112. When the water absorption sleeve 1112 is sleeved on the shaft 1111, the groove 1111a cooperates with the protrusion 1112a.

[0060] In this way, the water absorption sleeve 1112 can be positioned relative to the shaft 1111 through the cooperation between the groove 1111 a and the protrusion 1112 a , so that the water absorption sleeve 1112 can reliably rotate along with the shaft 1111 .

[0061] Combine Figure 12 In some embodiments, each first water removal assembly 11 further includes a rotatable clamping gear 112 , one end of the rotating shaft of each clamping gear 112 is connected to one end of the rotating shaft of the first water absorbing member 111 , and at least a portion of the propulsion channel AA is formed between the two clamping gears 112 . When the charging gun 220 is inserted into or removed from the charging socket 2101 , each clamping gear 112 can engage with the rack 2202 on the side wall of the charging gun 220 for rotation.

[0062] That is to say, when the charging gun 220 is inserted into or removed from the charging socket 2101, the charging gun 220 can enter the propulsion channel AA between the two clamping gears 112, so that the rack 2202 on the side wall of the charging gun 220 can cooperate with the clamping gear 112, driving the clamping gear 112 to rotate, thereby driving the first water absorbing part 111 coaxially connected to the clamping gear 112 to rotate, and then the first water absorbing part 111 removes water from the side wall of the charging gun 220.

[0063] It should be noted that there are at least two racks 2202 on the side wall of the charging gun 220 . The two racks 2202 are respectively located on the two side walls of the charging gun 220 to mesh with a corresponding clamping gear 112 .

[0064] Therefore, by setting the rack 2202 on the side wall of the charging gun 220 to mesh with the clamping gear 112, not only can the clamping gear 112 rotate when the charging gun 220 is inserted into or removed from the charging socket 2101, thereby driving the first water absorbing member 111 to rotate and absorb water on the charging gun 220, but the charging gun 220 can also be restricted by the two clamping gears 112, so that the charging gun 220 will not easily fall off the charging socket 2101 during the process of inserting or removing the charging socket 2101.

[0065] Specifically, the clamping gear 112 is located at the bottom of the first water-absorbing member 111. The rack 2202 of the charging gun 220 is located at the bottom of the sidewall of the charging gun 220, extending from the charging port 2201 of the charging gun 220 to a position near the handle 2203 of the charging gun 220. This provides a sufficient mating length to ensure that the charging gun 220 is stably restrained throughout the entire process of being inserted into or removed from the charging jack 2101, improving the reliability of water removal.

[0066] See Figures 8 to 11 Furthermore, each first water removal component 11 also includes an elastic member 113 and a limiting member 114. The limiting member 114 is connected to the end of the clamping gear 112 axially facing away from the first water absorbing member 111. The elastic member 113 is connected between the limiting member 114 and the inner wall of the charging socket 2101 along the width direction of the charging socket 2101, and can be compressed when the clamping gear 112 is engaged with the rack 2202 of the charging gun 220, thereby providing a pre-tightening force to keep the clamping gear 112 and the rack 2202 engaged.

[0067] In this way, the elastic restoring force of the elastic member 113 during compression pushes the two clamping gears 112 toward opposite directions to squeeze the charging gun 220 , thereby keeping the two clamping gears 112 engaged with the corresponding two racks 2202 , thereby improving the stability of the engagement.

[0068] Specifically, the elastic member 113 may be a spring. In other embodiments, the elastic member 113 may also be elastic rubber or the like.

[0069] Specifically, a connecting bearing 115 is provided at one end of the clamping gear 112 axially facing away from the first water absorbing member 111, and the limiting member 114 is connected to the connecting bearing 115. The connecting bearing 115 has a larger connection area, making the connection between the limiting member 114 and the connecting bearing 115 more reliable.

[0070] Furthermore, a limiting groove 2101 a extending along the width direction of the charging socket 2101 is formed on the inner wall of the charging socket 2101 , and the limiting member 114 is limited in the limiting groove 2101 a .

[0071] The limiting groove 2101a can limit the movement of the limiting member 114, thereby enabling the clamping gear 112 and the first water absorbing member 111 connected to the limiting member 114 to move stably, and the elastic member 113 to perform compression and extension movements stably.

[0072] Optionally, the cross-sectional shape of the limiting groove 2101a is T-shaped, and the outer contour of the limiting member 114 matches the inner contour of the limiting groove 2101a. The T-shaped limiting groove 2101a can limit the limiting member 114 in two directions perpendicular to the width of the charging socket 2101. Therefore, when the clamping gear 112 is subjected to uneven force, the movement of the clamping gear 112 can be restricted, thereby preventing the clamping gear 112 from tilting and affecting the insertion or removal stability of the charging gun 220. This further improves the movement stability of the limiting member 114, the clamping gear 112, and the first water absorbing member 111.

[0073] Combine Figure 6 、 Figure 7 、 Figure 13 and Figure 14 In an embodiment of the present application, the second water removal mechanism 20 includes two rotatable second water removal components 21, and the two second water removal components 21 are arranged opposite to each other along the width direction of the charging socket 2101. When the charging gun 220 is inserted into the charging socket 2101, the charging port 2201 of the charging gun 220 can abut against the two second water removal components 21 to push the two second water removal components 21 to rotate relative to each other to remove water from the end face of the charging gun 220, that is, the charging port 2201.

[0074] When the charging gun 220 is inserted into the charging socket 2101, it first passes through the propulsion channel AA, and then the charging port 2201 contacts the two second water removal components 21. As the charging gun 220 continues to advance, the charging port 2201 is subjected to friction on the surfaces of the two second water removal components 21, which in turn drives the two second water removal components 21 to rotate relative to each other, thereby removing water from the charging port 2201. Compared with the direct static bonding method, this water removal method is easier to remove water from the charging port 2201 and improves the reliability of removal. In addition, the relative rotation of the two second water removal components 21 enables the charging gun 220 to enter the rear of the second water removal components 21, that is, deeper into the charging socket 2101, thereby better protecting the charging port 2201.

[0075] Specifically, the second water removal component 21 is provided with a second water absorbing part 211 on the side facing the first water removal mechanism 10 . When the charging gun 220 is inserted into the charging socket 2101 , the end face of the charging gun 220 , that is, the charging port 2201 , can abut against the second water absorbing part 211 .

[0076] In this way, the second water absorber 211 can absorb water on the charging port 2201 of the charging gun 220 , thereby removing the water on the charging port 2201 of the charging gun 220 .

[0077] Specifically, the second water absorbent member 211 may be a sponge water absorbent member. In other embodiments, the second water absorbent member 211 may also be a water absorbent member made of other materials with adsorption properties.

[0078] Optionally, the contour of the surface of the second water absorber 211 facing the charging port 2201 of the charging gun 220 is adapted to the contour of the charging port 2201. In this way, the charging port 2201 can be fully absorbed.

[0079] In some embodiments, the second water removal component 21 further includes a baffle 212 and a rebound stirring roller 213, one side of the baffle 212 is rotatably disposed in the charging socket 2101 through the rebound stirring roller 213, and the second water absorbing member 211 is disposed on the side of the baffle 212 facing the first water removal mechanism 10.

[0080] When the charging gun 220 is inserted into the charging socket 2101, the charging port 2201 of the charging gun 220 abuts against the second water absorbing member 211, thereby pushing the baffle 212 to rotate about the rebound agitator 213, thereby removing water from the charging port 2201. Furthermore, when the charging gun 220 is removed from the charging socket 2101, the charging port 2201 of the charging gun 220 no longer abuts against the second water absorbing member 211, and the baffle 212 can rotate under the elastic restoring force of the rebound agitator 213. The two baffles 212 can effectively close the charging socket 2101, thereby preventing rainwater from entering the area behind the baffles 212 and improving the sealing performance of the charging body 210.

[0081] Furthermore, the second water absorbent member 211 is detachably connected to the baffle 212. When the second water absorbent member 211 is used for a long time, it may be soaked with water and have poor performance. The staff can remove it and replace it with a new one to ensure the water absorption efficiency.

[0082] Specifically, the second water absorbing member 211 can be attached to the baffle 212 by means of Velcro, so that the second water absorbing member 211 can be disassembled.

[0083] More specifically, the second absorbent member 211 is provided with a first Velcro 2111, and the baffle 212 is provided with a second Velcro 2121. The first Velcro 2111 and the second Velcro 2121 are attached to each other. Therefore, the second absorbent member 211 can be replaced by tearing off the first Velcro 2111 and the second Velcro 2121, thereby improving the convenience and efficiency of replacement.

[0084] See Figure 6 、 Figure 7 and Figure 11 In an embodiment of the present application, the charging device waterproof device 100 further includes a closing mechanism 30, which is located between the first water removal mechanism 10 and the second water removal mechanism 20 along the depth direction of the charging socket 2101. The closing mechanism 30 is linked to the first water absorbing member 111 to open or close the portion of the charging socket 2101 connecting the first water removal mechanism 10 and the second water removal mechanism 20 when the first water absorbing member 111 rotates.

[0085] The closing mechanism 30 is a mechanism capable of closing the passage. Specifically, during the implementation of this application, when the charging gun 220 is inserted into the charging socket 2101, the first water absorbing member 111 rotates forwardly, driven by the charging gun 220, thereby driving the closing mechanism 30 to open the portion of the charging socket 2101 connecting the first water removal mechanism 10 and the second water removal mechanism 20. When the charging gun 220 is removed from the charging socket 2101, the first water absorbing member 111 rotates backward, driven by the charging gun 220, thereby driving the closing mechanism 30 to close the portion of the charging socket 2101 connecting the first water removal mechanism 10 and the second water removal mechanism 20.

[0086] In this way, during the process of inserting the charging gun 220 into the charging socket 2101, the closing mechanism 30 can open the part of the charging socket 2101 connecting the first water removal mechanism 10 and the second water removal mechanism 20, so that the charging gun 220 can move further into the deeper part of the charging socket 2101, so that its end face contacts the second water removal mechanism 20, thereby realizing water removal from the end face of the charging gun 220. In the process of pulling the charging gun 220 out of the charging socket 2101, the closing mechanism 30 can close the part of the charging socket 2101 connecting the first water removal mechanism 10 and the second water removal mechanism 20, thereby preventing rainwater from entering the second water removal mechanism 20 and the rear of the second water removal mechanism 20, thereby improving the reliability of the subsequent water removal of the second water removal mechanism 20 and the sealing of the charging body 210.

[0087] Furthermore, the closing mechanism 30 includes two closing assemblies 31 positioned opposite each other along the width of the charging socket 2101. Each closing assembly 31 includes a folding door 311 with elastic folding properties, a pull cord 312, and a rotatable roller 313. The folding door 311 is foldable along the width of the charging socket 2101. One end of the pull cord 312 is connected to the folding door 311, and the other end passes through the roller 313 and is connected to the rotating shaft of the corresponding first absorbent member 111. When the charging gun 220 is inserted into the charging socket 2101 and the first absorbent member 111 rotates, the pull cord 312 can be wrapped around the rotating shaft of the first absorbent member 111 and contracted, causing the folding door 311 to be elastically compressed and folded. When the charging gun 220 is removed from the charging socket 2101 and the first absorbent member 111 rotates, the pull cord 312 can be unwound from the rotating shaft of the first absorbent member 111 and extended, causing the folding door 311 to open under the action of the elastic restoring force.

[0088] In this way, by providing the folding door 311, the pull rope 312 and the rotatable roller 313, the closing component 31 can follow the rotation of the first water absorbing member 111 and thereby reliably open or close the portion of the charging socket 2101 between the first water removal mechanism 10 and the second water removal mechanism 20.

[0089] Optionally, one end of each folding door 311 away from the other folding door 311 is rotatably connected to the charging socket 2101 through a connecting rod 314 .

[0090] In other embodiments, the folding door 311 may be replaced by a water-blocking curtain, a rolling curtain, etc. The pull rope 312 may also be replaced by other connecting rod mechanisms, sprocket chains, etc.

[0091] Optionally, one end of the pull cord 312 is fixed to an end of the corresponding folding door 311 close to the other folding door 311. In this way, when the pull cord 312 is retracted, the entire folding door 311 can be folded in a direction away from the other folding door 311.

[0092] More specifically, each closing component 31 includes a sealing strip 315 and a connecting block 316. The sealing strip 315 is fixed to one end of a corresponding folding door 311 close to another folding door 311. The connecting block 316 is fixed to the sealing strip 315. One end of the pull rope 312 is fixed to the connecting block 316.

[0093] When the pull cord 312 is retracted, it can pull the connecting block 316, which in turn pulls the sealing strip 315, causing the folding door 311 to fold away from the other folding door 311. In addition, when the closing mechanism 30 closes the portion of the charging jack 2101 connecting the first water removal mechanism 10 and the second water removal mechanism 20, the sealing strips 315 on the two closing components 31 can abut against each other to improve sealing reliability.

[0094] Optionally, a connecting groove 2101b is defined along the inner wall of one side of the charging socket 2101 along its width, and a roller 313 is rotatably disposed within the connecting groove 2101b. The rotating axis of the roller 313 is parallel to the rotating axis of the first water-absorbing member 111. This ensures that the pull cord 312 is sufficiently long to reliably fold the folding door 311, while also minimizing interference between the roller 313 and other components.

[0095] Optionally, each closure assembly 31 includes multiple, for example two, rollers 313. The multiple rollers 313 are arranged side by side along the depth direction of the charging receptacle 2101, and the pull cord 312 can simultaneously pass around the multiple rollers 313. Providing multiple rollers 313 increases the distance between the closure mechanism 30 and the first water removal mechanism 10 along the depth direction of the charging receptacle 2101, thereby reducing positional interference between the two and more reliably guiding the pull cord 312 to retract and extend.

[0096] Combine Figure 9Optionally, the first water-absorbing member 111 further includes a rotating disk 1113 disposed at one end of the shaft 1111. The shaft 1111 and the rotating disk 1113 are coaxially disposed and serve as at least a portion of the rotating axis of the first water-absorbing member 111. The drawstring 312 can be connected to the rotating disk 1113 so that the drawstring 312 can be wound around or unwound from the rotating disk 1113 when the first water-absorbing member 111 rotates.

[0097] In addition, a tray 1114 is provided at one end of the turntable 1113 away from the shaft 1111. The tray 1114 is coaxially arranged with the turntable 1113, and the diameter of the tray 1114 is larger than the diameter of the turntable 1113. In this way, the pull rope 312 wrapped around the turntable 1113 can be axially limited to prevent the pull rope 312 from being unable to be reliably wrapped around the turntable 1113.

[0098] In some embodiments, in order to improve the sealing reliability of the folding door 311, each closing component 31 also includes a magnetic strip 317, and the magnetic strip 317 is fixed to one end of the corresponding folding door 311 close to the other folding door 311. When the closing mechanism 30 closes the part of the charging socket 2101 connecting the first water removal mechanism 10 and the second water removal mechanism 20, the magnetic strips 317 of the two closing components 31 are magnetically connected to each other.

[0099] Specifically, the magnetic strip 317 can be fixed on the end surface of the sealing strip 315 of each closing component 31 facing the other closing component 31.

[0100] To improve the reliability of the folding and opening of the folding door 311, in a specific embodiment of the present application, the closing mechanism 30 includes two sets of closing components 31. The two sets of closing components 31 are arranged opposite each other along the axial direction of the first water-absorbing member 111, and each set of closing components 31 includes two closing components 31. In this way, the closing components 31 can be arranged at both axial ends of the first water-absorbing member 111, so that both sides of the folding door 311 in the height direction can be subjected to the force of the contraction and release of the pull cord 312, thereby folding and opening accordingly.

[0101] In some embodiments, the closing mechanism 30 also includes an elastic pad 32 and an elastic plug 33. The inner wall of the charging socket 2101 is also provided with a movable groove 2101c. The bottom of the folding door 311 is located in the movable groove 2101c. The elastic pad 32 is also located in the movable groove 2101c, and is located on the side of the folding door 311 facing the second water removal mechanism 20 and is against the folding door 311. A connecting hole 321 is provided on the elastic pad 32, and the elastic plug 33 is clamped in the connecting hole 321 and elastically limited in the movable groove 2101c. In this way, the elastic pad 32 can be prevented from detaching from the movable groove 2101c when uneven force is applied, thereby improving the firmness of the elastic pad 32, so that it can be reliably abutted against the folding door 311 to keep the bottom of the folding door 311 in the movable groove 2101c.

[0102] Specifically, the elastic pad 32 and the elastic plug 33 can both be made of rubber.

[0103] See Figures 1 to 5 and Figure 12 Based on the same inventive concept, the present application further provides a charging device 200, comprising a charging body 210, a charging gun 220 connected to the charging body 210, and the charging device waterproof device 100 of any of the above embodiments. The charging body 210 has a charging socket 2101, the charging gun 220 can be inserted into or removed from the charging socket 2101, and the charging device waterproof device 100 is disposed in the charging socket 2101.

[0104] Since the charging equipment waterproof device 100 is arranged in the charging socket 2101, when the charging gun 220 is inserted into or unplugged from the charging socket 2101, the side walls of the charging gun 220 can be dewatered by the first dewatering mechanism 10, and the end face of the charging gun 220 can be further dewatered by the second dewatering mechanism 20. Therefore, water droplets, water stains, etc. on the surface of the charging gun 220 are reduced, thereby reducing the risk of water entering the interior of the charging gun 220, improving the charging performance and service life of the charging gun 220, and also improving the safety of users when using the charging gun 220 for charging.

[0105] Specifically, the charging body 210 includes a cabinet 2102 and an integrated module 2104 installed in the cabinet 2102. A cable 230 is provided on the outside of the cabinet 2102. The charging gun 220 is connected to the integrated module 2104 in the cabinet 2102 through the cable 230. The charging socket 2101 is opened on the cabinet 2102 and connects the outside and inside of the cabinet 2102.

[0106] Specifically, the cabinet 2102 includes a cabinet body 2105 and a cabinet door 2106. The cabinet body 2105 has a first opening. The cabinet door 2106 is hinged to the cabinet body 2105 via a first hinge 2107 to open or close the first opening. By opening the first opening, the integrated module 2104 can be exposed to allow inspection or maintenance of the integrated module 2104.

[0107] In addition, a fixing frame may be provided in the cabinet 2102 , and the integrated module 2104 may be provided on the fixing frame.

[0108] In some embodiments, the charging device 200 further includes a cooling device 240 and a ventilation pipe 250 connected to the cooling device 240 . The cooling device 240 is installed on the charging body 210 , and the ventilation pipe 250 connects the cooling device 240 and the charging socket 2101 .

[0109] The cooling device 240 can cool the surrounding air to form a cooling airflow or directly generate a cooling airflow.

[0110] After the charging gun 220 has just been used, the charging port 2201 of the charging gun 220 will overheat due to prolonged use. Therefore, when the charging gun 220 is inserted into the charging socket 2101, the ventilation pipe 250 can transport the cooling airflow generated by the cooling device 240 to the charging socket 2101, thereby cooling the charging port 2201 of the charging gun 220 in the charging socket 2101, thereby improving the service life of the charging gun 220.

[0111] Optionally, the cooling device 240 includes multiple cooling modules 241, which are spaced apart from each other. Specifically, the cooling module 241 can be a fan. The fan is fixed to the cabinet 2102 and can circulate surrounding air to form a cooling airflow, thereby cooling the charging port 2201 of the charging gun 220. In other embodiments, the cooling module 241 can also be a heat exchanger.

[0112] Optionally, the cabinet body 2105 further has a second opening, and the cabinet body 2102 further includes a mounting plate 2108, the cooling device 240 is mounted on the mounting plate 2108, and the mounting plate 2108 is hinged to the cabinet body 2105 via a second hinge to open or close the second opening.

[0113] In this way, the cooling device 240 on the mounting plate 2108 can be inspected or repaired by opening the second opening.

[0114] Optionally, the ventilation duct 250 in this embodiment is installed inside the cabinet 2102, with one end communicating with the end of the charging jack 2101 that is connected to the interior of the cabinet 2102. This arrangement reduces the complexity of installing the ventilation duct 250 on the wall of the cabinet 2102 and simplifies the structure of the cabinet 2102. The other end of the ventilation duct 250, away from the charging jack 2101, can be flexibly connected to the cooling device 240.

[0115] In some embodiments, the end of the ventilation tube 250 that is connected to the charging socket 2101 is also connected to the interior of the cabinet 2102 .

[0116] In this way, the cooling airflow can be diffused into the interior of the cabinet 2102 , thereby cooling the components inside the cabinet 2102 , such as the integrated module 2104 , and improving the operational reliability of the entire charging body 210 .

[0117] In some embodiments, the charging body 210 further includes a control screen 2109 , which is mounted on the outside of the cabinet 2102 and is communicatively connected to the integrated module 2104 .

[0118] In some embodiments, the charging device 200 further includes a rain shield 260, which is disposed outside the charging body 210 and at least covers the top of the charging socket 2101. This shields the charging socket 2101 on rainy days, reducing the risk of rainwater entering the charging socket 2101.

[0119] In some embodiments, the charging device 200 further includes a holder 270, which is positioned at the entrance of the charging receptacle 2101. The holder 270 has an insertion port for inserting the charging gun 220, and its inner contour matches the outer contour of the charging gun 220. Thus, the holder 270 not only supports and positions the charging gun 220, keeping it within the charging receptacle 2101, but also blocks rainwater from entering the charging receptacle 2101.

[0120] In order to better understand the embodiments of the present application, the following is a detailed introduction to the use process of the charging device waterproof device 100 of the present application:

[0121] When the user returns the charging gun 220 and inserts it into the charging socket 2101, the racks 2202 on either side of the bottom of the charging gun 220 press against and mesh with the two clamping gears 112. The elastic member 113 is compressed by the pressure of the charging gun 220, causing the two clamping gears 112 to remain meshed with the racks 2202 of the charging gun 220. As the charging gun 220 is pushed further in, the first water absorbent member 111 adheres to the sidewalls of the charging gun 220 and rotates with the rotation of the clamping gears 112, removing water from the sidewalls of the charging gun 220. As the charging gun 220 continues to advance, the folding door 311 folds under the action of the pull cord 312 connected to the rotating shaft of the first water-absorbing member 111, allowing the charging gun 220 to be pushed further into the charging socket 2101. The charging port 2201 of the charging gun 220 contacts the second water-absorbing member 211 on the baffle 212. The friction force pushes the baffle 212 to rotate about the rebound stirring roller 213, thereby removing water from the charging port 2201. At this point, the charging port 2201 of the charging gun 220 can be located behind the baffle 212 and connected to the ventilation pipe 250, thereby being cooled by the cold air supplied by the cooling device 240.

[0122] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application.
