Description

Technical Field

[0001] This utility model relates to the field of charging equipment technology, and in particular to a cleaning device. Background Technology

[0002] With the rapid popularization of new energy vehicles in the industrial sector, new energy heavy-duty trucks and new energy mining trucks are widely used. However, these trucks typically operate in dusty environments. Research has found that the terminals of charging sockets and charging gun pins are prone to dust accumulation in dusty environments. During frequent plugging and unplugging operations, these particles form a dense layer of dirt through mechanical friction, significantly increasing the contact resistance when the pins are engaged. This leads to a sharp rise in temperature during charging, greatly reducing the lifespan of the charging equipment and potentially causing safety hazards. Therefore, it is necessary to clean the charging sockets and charging gun pins regularly. Current cleaning methods typically involve operators wiping with a cloth, which is inconvenient, time-consuming, and difficult to clean thoroughly due to the lack of specialized cleaning tools.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0031] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0032] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0033] In related technologies, such as Figure 1As shown, the end face of the charging gun 200 typically has a slot 6, and the pins 7 of the charging gun 200 are located within the slot 6. The charging base has a positioning post, and the socket of the charging base is located on the positioning post. When the charging gun 200 and the charging base are connected, the positioning post of the charging base extends into the slot 6 of the charging gun 200, and simultaneously, the pins 7 are inserted into the socket to achieve electrical connection between the charging gun 200 and the charging base. When cleaning the pins 7 of the charging gun 200, due to the limited space between the slot wall of the slot 6 and the pins 7, directly cleaning the pins 7 with a cloth is not only time-consuming but also makes it difficult to clean the pins 7 thoroughly. Similarly, when cleaning the socket of the charging base, due to the size limitations of the socket, directly cleaning with a cloth also results in a time-consuming process and incomplete cleaning.

[0034] Based on the above issues, please refer to the following: Figures 1 to 5 As shown, this utility model proposes a cleaning device 100 for cleaning the charging structure of a charging gun 200 or a charging base. The charging gun 200 is provided with a pin 7, and the charging base is provided with a socket. The cleaning device 100 includes a first cleaning component 1, a second cleaning component 2, and a hand-driven assembly 3. The first cleaning component 1 is provided with a first cleaning head 11, which is used to clean the pin 7. The second cleaning component 2 is connected to the end of the first cleaning component 1 away from the first cleaning head 11, and is provided with a second cleaning head 21, which is used to clean the socket. The hand-driven assembly 3 is located between the first cleaning component 1 and the second cleaning component 2, and is used to drive the first cleaning component 1 and the second cleaning component 2 to rotate.

[0035] In this embodiment, the first cleaning component 1 and the second cleaning component 2 are connected. The two opposite ends of the first cleaning component 1 and the second cleaning component 2 are respectively provided with a first cleaning head 11 and a second cleaning head 21. When cleaning the pin 7 of the charging gun 200, the first cleaning head 11 of the first cleaning component 1 can be pressed tightly against the pin 7, and then the first cleaning component 1 can be rotated by the hand-drive assembly 3 to complete the cleaning of the pin 7. Similarly, when cleaning the socket of the charging dock, the second cleaning head 21 can be pressed tightly against the inner wall of the socket, and then the second cleaning component 2 can be rotated by the hand-drive assembly 3 to complete the cleaning of the socket. Users can use the cleaning device 100 of this application to clean the plug or the socket. When cleaning the pin 7 and the socket with the cleaning device 100 of this application, users do not need to manually rotate the first cleaning component 1 and the second cleaning component 2 directly. Instead, the first cleaning head 11 is driven to rotate around the pin 7 or the second cleaning head 21 is driven to rotate inside the socket by the hand drive assembly 3, thereby removing impurities from the pin 7 and the socket. This can improve the cleaning efficiency of the pin 7 or the socket, reduce the contact resistance of the pin 7 and the socket, and ensure the stability and safety of electrical transmission between the pin 7 and the socket.

[0036] Understandably, due to the structural differences between the pins 7 of the charging gun 200 and the socket of the charging base, the first cleaning head 11 and the second cleaning head 21 can be respectively shaped to correspond to the pins 7 and the socket, so that the first cleaning head 11 can make good contact with the outer surface of the pins 7 and the second cleaning head 21 can make good contact with the inner surface of the socket, thus avoiding inadequate cleaning.

[0037] In actual implementation, the first cleaning head 11 and the second cleaning head 21 are coaxially arranged. The hand drive assembly 3 drives the first cleaning head 11 or the second cleaning head 21 to rotate around the axis to remove impurities from the surface of the pin 7 or the socket.

[0038] Optionally, the first cleaning component 1 and the second cleaning component 2 can be detachably connected by the engagement of internal and external threads, or they can be detachably connected by a snap-fit ​​structure; no specific limitation is made here. The detachable connection of the first cleaning component 1 and the second cleaning component 2 allows the user to replace the damaged first cleaning component 1 or the second cleaning component 2, which helps to reduce usage costs.

[0039] In an embodiment of this utility model, the hand-driven assembly 3 includes a connecting rod 31, a reset elastic element 32, and a pull rope 33. The connecting rod 31 is connected to the first cleaning element 1 and / or the second cleaning element 2. One end of the reset elastic element 32 is connected to the connecting rod 31, and the pull rope 33 is connected to the other end of the reset elastic element 32.

[0040] In this embodiment, as Figure 1 and Figure 2 As shown, the connecting rod 31 can be connected only to the first cleaning component 1, only to the second cleaning component 2, or simultaneously to both. When it is necessary to drive the first cleaning head 11 and the second cleaning head 21 to rotate, the user pulls the pull cord 33. The tension of the pull cord 33 is transmitted to the reset elastic element 32. After being pulled, the reset elastic element 32 undergoes elastic deformation, simultaneously driving the connecting rod 31 to rotate. The connecting rod 31 then drives the first cleaning component 1 and the second cleaning component 2 to rotate. When the user releases the pull cord 33, the reset elastic element 32 uses its own elastic restoring force to reset the pull cord 33, preparing for the next cleaning operation.

[0041] Understandably, the connecting rod 31 is arranged along the axial direction of the first cleaning head 11 and the second cleaning head 21 so that the hand drive assembly 3 can rotate accurately around the axis, ensuring the cleaning effect of the first cleaning head 11 and the second cleaning head 21 while reducing the possibility of the first cleaning head 11 damaging the pin 7 and the second cleaning head 21 damaging the socket.

[0042] It should be noted that after the user tightly fits the first cleaning head 11 with the pin 7, the hand-drive assembly 3 drives the first cleaning head 11 to rotate over the friction between the first cleaning head 11 and the pin 7. At the same time, the hand-drive assembly 3 also drives the second cleaning component 2 to rotate. Similarly, when the user tightly fits the second cleaning head 21 with the socket, the hand-drive assembly 3 drives the second cleaning head 21 to rotate over the friction between the second cleaning head 21 and the socket. At the same time, the hand-drive assembly 3 also drives the first cleaning component 1 to rotate.

[0043] In an embodiment of this utility model, one end of the reset elastic member 32 is provided with an opening 321, the periphery of the connecting rod 31 is provided with a screw hole 311, and the hand drive assembly 3 also includes a screw 34, which passes through the opening 321 and is threadedly engaged with the screw hole 311.

[0044] In this embodiment, as Figure 1 , Figure 2 and Figure 5 As shown, the reset elastic element 32 is fastened to the peripheral side of the connecting rod 31 by screws 34, so that the reset elastic element 32 can be stably connected to the connecting rod 31, and at the same time, it is convenient to replace the reset elastic element 32 when it fails or ages, which is beneficial to the maintenance of the cleaning device 100.

[0045] In an embodiment of this utility model, a cavity 4 is provided between the first cleaning component 1 and the second cleaning component 2, and the hand drive assembly 3 is provided in the cavity 4. The first cleaning component 1 and / or the second cleaning component 2 are also provided with a through hole 13 communicating with the cavity 4, and at least part of the hand pull rope 33 extends out of the cavity 4 through the through hole 13.

[0046] In this embodiment, as Figure 1 , Figure 2 and Figure 5 As shown, a relatively closed cavity 4 is formed between the first cleaning component 1 and the second cleaning component 2. The hand drive assembly 3 is disposed within the cavity 4. This prevents external dust and dirt from corroding the hand drive assembly 3, ensuring the reliability of the hand drive assembly 3 during operation and extending its service life. Simultaneously, the cavity 4 also helps reduce the shaking and noise of the hand drive assembly 3 during use. The end of the pull rope 33 away from the reset elastic component 32 extends out of the cavity 4 through the through hole 13 for easy pulling by the operator.

[0047] Understandably, the cavity wall of the cavity 4 can be abutted against the reset elastic element 32, which plays a certain guiding role in the deformation and reset of the reset elastic element 32, so that the reset elastic element 32 can deform and reset around the connecting rod 31.

[0048] In actual implementation, the through hole 13 in this embodiment can be set on the first cleaning member 1, or on the second cleaning member 2, or it can be formed by the first cleaning member 1 and the second cleaning member 2 enclosing each other.

[0049] Optionally, the edge of the through hole 13 is chamfered to reduce wear on the pull rope 33 during pulling and resetting, and to extend the service life of the pull rope 33.

[0050] Optionally, the end of the pull cord 33 away from the reset elastic element 32 is wrapped to form a pull ring, so that the user can pull the pull cord 33.

[0051] In an embodiment of this utility model, the first cleaning component 1 is provided with a groove 12, and the second cleaning component 2 covers the opening of the groove 12 to enclose the cavity 4.

[0052] In this embodiment, as Figures 2 to 4 As shown, the second cleaning component 2 covers the groove opening of the first cleaning component 1's recess 12 to jointly enclose and form the cavity 4. It can be understood that in this embodiment, a through hole 13 is provided on the first cleaning component 1.

[0053] In actual implementation, the second cleaning component 2 may have a groove, and the first cleaning component 1 may cover the opening of the groove in the second cleaning component 2 to form a cavity 4. Alternatively, both the first cleaning component 1 and the second cleaning component 2 may have grooves, with the openings of the grooves facing each other to form a cavity 4.

[0054] In an embodiment of this utility model, the first cleaning component 1 is provided with a first threaded hole 14, the second cleaning component 2 is provided with a second threaded hole 22, and the connecting rod 31 is provided with an external thread, which is threadedly engaged with the first threaded hole 14 and the second threaded hole 22.

[0055] In this embodiment, as Figures 2 to 4 As shown, the first cleaning component 1 and the second cleaning component 2 are connected by a connecting rod 31. The first cleaning component 1 has a first threaded hole 14, and the external thread of the connecting rod 31 is threaded into the first threaded hole 14, so that the connecting rod 31 can be firmly connected to the first cleaning component 1. Similarly, the second cleaning component 2 has a second threaded hole 22, and the external thread of the connecting rod 31 is threaded into the second threaded hole 22, so that the connecting rod 31 can be firmly connected to the second cleaning component 2. This achieves a detachable connection between the first cleaning component 1 and the second cleaning component 2, while also ensuring that the hand-drive assembly 3 can effectively drive the first cleaning component 1 and the second cleaning component 2 to rotate.

[0056] Understandably, the external threads of the connecting rod 31 can be provided at both ends of the connecting rod 31, and the middle part of the connecting rod 31 is used for connection of the reset elastic element 32. Optionally, the first cleaning element 1 can form a positioning post, and the positioning post is provided with a first threaded hole 14 to facilitate the connection of the connecting rod 31.

[0057] In an embodiment of this utility model, the reset elastic element 32 is a spring.

[0058] In this embodiment, as Figure 2 and Figure 5 As shown, the spring-loaded spring, acting as the reset elastic element 32, possesses excellent elastic properties. When the end of the spring-loaded spring connected to the pull cord 33 is pulled by an external force, it can rotate circumferentially under the action of the external force and store elastic potential energy as it is pulled. When the external force is released, it quickly returns to its original shape, providing a stable reset power for the hand-driven assembly 3. This ensures that the cleaning device 100 can rotate and reset smoothly during use, improving the convenience and efficiency of cleaning.

[0059] Understandably, when the first cleaning head 11 and the second cleaning head 21 are rotated by the hand-driven assembly 3, the user pulls the pull cord 33, causing the spring to gradually unwind and deform, simultaneously rotating the connecting rod 31. The connecting rod 31 then rotates the first cleaning head 11 and the second cleaning head 21. The first cleaning head 11 and the second cleaning head 21 effectively remove dust, dirt, and other impurities from the pins 7 and the sockets. When the pull cord 33 is released, the spring rebounds and quickly returns to its original shape, causing the connecting rod 31 to rotate in the opposite direction, again rotating the first cleaning head 11 and the second cleaning head 21 to clean the pins 7 and the sockets, effectively improving the cleaning efficiency of the cleaning device 100.

[0060] Optionally, the reset elastic element 32 can also be a coil spring.

[0061] In embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the first cleaning component 1 includes a first connecting portion 15 and a first cleaning head 11 connected to each other. The cross-sectional area of ​​the first connecting portion 15 gradually increases from the end closer to the first cleaning head 11 to the end farther away from the first cleaning head 11.

[0062] In this embodiment, the end of the first connecting portion 15 facing away from the first cleaning head 11 is used to connect with the second cleaning component 2. The variable cross-section of the first connecting portion 15 can improve the connection strength between the first cleaning component 1 and the second cleaning component 2, enabling it to withstand greater forces during rotational cleaning and making it less prone to deformation or damage. At the same time, the variable cross-section of the first connecting portion 15 can also prevent the user's view from being obstructed when the first cleaning head 11 and the pin 7 are engaged, which is beneficial for the user to accurately engage the first cleaning head 11 and the pin 7.

[0063] Optionally, the first connecting part 15 and the first cleaning head 11 can be integrally formed and can be detachably connected by means of threaded engagement or snap-fit ​​structure, so as to replace the first cleaning head 11 according to the size of the pin 7.

[0064] In embodiments of this utility model, such as Figure 2 and Figure 4As shown, the second cleaning component 2 includes a second connecting portion 23 and a second cleaning head 21 connected together. The cross-sectional area of ​​the second connecting portion 23 gradually increases from the end closer to the second cleaning component 2 to the end farther away from the second cleaning component 2.

[0065] In this embodiment, the end of the second connecting portion 23 facing away from the second cleaning head 21 is used to connect with the first cleaning component 1. The variable cross-section of the second connecting portion 23 can improve the connection strength between the second cleaning component 2 and the first cleaning component 1, enabling it to withstand greater force during rotational cleaning and making it less prone to deformation or damage. At the same time, the variable cross-section of the second connecting portion 23 can also prevent the user's view from being obstructed when the second cleaning head 21 is abutted against the inner wall of the socket, which is beneficial for the user to accurately abut against the inner wall of the pin 7.

[0066] Optionally, the second connector and the second cleaning head 21 can be integrally formed and can be detachably connected by means of threaded engagement or snap-fit ​​structure, so as to replace the second cleaning head 21 according to the size of the socket.

[0067] In embodiments of this utility model, such as Figure 3 As shown, the first cleaning head 11 is provided with a cleaning recess 111, which is used for the insertion of the pin 7.

[0068] When cleaning the pin 7, the first cleaning head 11 is inserted into the slot 6 where the pin 7 is located. At the same time, the cleaning recess 111 precisely matches the shape of the pin 7 so that the pin 7 is inserted into the cleaning recess 111 and closely abuts against the cleaning recess 111. The first cleaning head 11 can closely fit the surface of the pin 7 so as to achieve all-round cleaning of the pin 7.

[0069] Optionally, the edges of the cleaning recess 111 may be chamfered to facilitate the insertion of the pin 7.

[0070] In an embodiment of this utility model, the second cleaning head 21 is provided with a cleaning protrusion 211, which is used to extend into the socket. When cleaning the socket, the cleaning protrusion 211 extends into the socket and abuts tightly against the inner wall of the socket to effectively remove dust and dirt from the socket and ensure cleaning effect.

[0071] Optionally, the edges of the cleaning protrusion 211 may be chamfered to facilitate insertion into the socket.

[0072] In an embodiment of this utility model, the surface of the first cleaning head 11 and / or the second cleaning head 21 is detachably covered with a cleaning cloth 5.

[0073] In this embodiment, as Figure 2As shown, the cleaning cloth 5 has excellent cleaning performance, capable of adsorbing and wiping away impurities from the outer surface of the pin 7 and the inner surface of the socket. When cleaning the pin 7, the inner surface of the first cleaning head 11 is covered with the cleaning cloth 5, which is in close contact with the pin 7. The hand-driven assembly 3 can drive the first cleaning head 11 to rotate the cleaning cloth 5, thus cleaning the surface of the pin 7. Similarly, when cleaning the socket, the outer surface of the second cleaning head 21 is covered with the cleaning cloth 5, which is in close contact with the inner wall of the socket. The hand-driven assembly 3 can drive the second cleaning head 21 to rotate the cleaning cloth 5, thus cleaning the inner wall of the socket. It is understood that the cleaning cloth 5 is made of a flexible material, allowing for better contact with the outer surface of the pin 7 and the inner surface of the socket, effectively ensuring the cleaning effect on the pin 7 and the socket.

[0074] This avoids direct contact between the first cleaning head 11 and the pin 7, and between the second cleaning head 21 and the inner wall of the socket, thus preventing wear caused by friction between the first cleaning head 11 and the pin 7, and between the second cleaning head 21 and the inner wall of the socket. At the same time, the detachable design of the cleaning cloth 5 allows users to wash or replace the dirty cleaning cloth 5 as needed, ensuring the continuity and stability of the cleaning effect.

[0075] Optionally, the cleaning cloth 5 can be sleeved, fitted onto the first cleaning head 11 and / or the second cleaning head 21 via an interference fit. For example, when the cleaning cloth 5 is on the first cleaning head 11, it fits onto the outer wall or end wall of the cleaning recess 111 and extends into the cleaning recess 111, covering its inner wall. When the cleaning cloth 5 is on the second cleaning head 21, it fits directly onto the cleaning protrusion 211. Alternatively, the cleaning cloth 5 can be detachably fixed to the first cleaning head 11 and / or the second cleaning head 21 using quick-release methods such as Velcro or magnets. This further reduces the possibility of the cleaning cloth 5 loosening or falling off during the cleaning process, ensuring the stability and reliability of the cleaning effect. Optionally, the cleaning cloth 5 can also be covered with other materials.

[0076] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
