Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, specifically to an adsorption-compatible charging gun. Background Technology

[0002] The advent of automobiles has brought convenience to people's travel. For example, compared with walking, people travel by car, which greatly shortens the time spent reaching their destination and improves the comfort of travel, thus making automobiles more widespread. With the continuous development of social technology, new energy vehicles have appeared on the market. New energy vehicles refer to automobiles that use unconventional vehicle fuels as a power source and integrate advanced technologies in vehicle power control and drive, forming automobiles with advanced technical principles, new technologies, and new structures. Pure electric vehicles belong to the category of new energy vehicles, and pure electric vehicles mainly rely on electric energy for driving.

[0003] Existing new energy vehicles are usually charged by charging stations installed on the road. Some charging stations are installed outdoors. On the one hand, when charging in the rain, water can easily get into the charging gun and the car's charging port, and rainwater can easily damage the electrical equipment. In order to solve the problem of charging in the rain, various rainproof devices have been proposed in the existing technology.

[0004] For example, Chinese utility model patent CN221282453U discloses a rainproof plug for charging new energy vehicles, which prevents rainwater from entering the charging port of the car during light rain by setting a rain-catching structure on the top of the charging gun. However, this rainproof device is completely ineffective in heavy rain.

[0005] For example, Chinese utility model patent CN118352852A discloses a charging gun that uses a waterproof rubber ring at the pins on the charging gun head. However, this rainproof measure requires simultaneous improvements to the charging port on the car.

[0006] A rain cover was created using ordinary plastic. However, this rain cover is very difficult to store, and the rain cover and charging gun need to be stored separately, taking up a lot of space. This significantly impacts the user experience, especially for cars with limited space.

[0007] Furthermore, existing methods of locking the charging gun to the car's charging port involve using a downward-facing hook or latch on the top of the charging gun to engage with a slot inside the charging port. Extensive research has revealed that, over time, the hook or latch mechanism concentrates all stress at a single point, leading to wear during insertion and removal. This can cause the hook or latch to loosen or even become loose, affecting charging performance. Utility Model Content

[0008] The purpose of this invention is to provide an adsorbent charging gun to partially solve or alleviate at least one of the problems mentioned in the background art, so as to ensure the stability between the charging gun and the charging port during use.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] This utility model provides an adsorbent charging gun, comprising a charging gun body, a mounting ring that can be fitted onto the charging gun body, a rain cover detachably provided on one side of the mounting ring to prevent rainwater from entering the car charging port, a magnetic ring for adsorbing onto the car body on the side of the rain cover away from the mounting ring, and a rainproof telescopic sleeve detachably provided on the other side of the mounting ring; wherein, at least one mounting block is fixedly provided on the mounting ring, each mounting block having a cavity inside, and a cooling fan for dissipating heat from the charging gun body is provided in the cavity; a second fixing groove is provided on the side of the mounting ring near the rain cover, and a first fixing ring is provided on the side near the rainproof telescopic sleeve; a second fixing ring that can engage with the second fixing groove is provided on the side of the rain cover near the mounting ring, and a first fixing groove that can engage with the first fixing ring is provided on the side of the rainproof telescopic sleeve near the mounting ring;

[0011] The charging gun further includes: an adsorption fixing module, which includes a fourth fixing ring that can be engaged with the second fixing groove, and a plurality of suction cups, each of which is fixedly connected to the fourth fixing ring by a connecting line;

[0012] When the fourth fixing ring engages with the second fixing groove, the adsorption fixing module is detachably mounted on the mounting ring and adsorbed onto the car body by the suction cup; or...

[0013] When the second fixing ring engages with the second fixing groove, the rain cover is detachably mounted on the mounting ring.

[0014] This new energy vehicle charging gun uses a cooling fan to dissipate heat from the charging gun body. During use, most of the heat released by the charging gun body during charging is retained inside the rain cover. At this time, the cooling fan is driven to rotate to quickly expel the heat from the rain cover. Then, outside air enters the rain cover through the rain cover telescopic sleeve, realizing air cooling circulation, thereby preventing the charging gun body from being damaged due to excessively high temperature over a long period of time.

[0015] This invention features a mounting ring that fits onto the charging gun, with a large-diameter rainproof telescopic sleeve on one side. A dust cover is also provided. During charging, a cooling fan on the mounting ring dissipates heat, protecting the charging gun from overheating. When not charging, the dust cover can be installed on the mounting ring to prevent dust from entering the charging head and to avoid damage to the exposed head caused by collisions during vehicle movement or bumpy conditions. Furthermore, the rainproof telescopic sleeve has a certain length (e.g., in the retracted state, it covers the part of the charging gun head connected to the wire, and a small portion of the wire (e.g., 1 / 5 of the wire); when fully extended, it covers the part of the charging gun head connected to the wire, and a portion of the wire (e.g., 3 / 5 of the wire)). This allows the wire to be retracted into the rainproof telescopic sleeve, forming a storage device with the dust cover, mounting ring, and rainproof telescopic sleeve.

[0016] Preferably, there are 5 suction cups, which are evenly distributed on the fourth fixing ring.

[0017] Preferably, it further includes: a dust cover, the dust cover including a circular base plate and an annular sidewall disposed on the base plate, wherein the sidewall away from the base plate is provided with a third fixing ring that can engage with the second fixing groove; the base plate is provided with a fifth fixing groove that can engage with the fourth fixing ring;

[0018] When the third fixing ring engages with the second fixing groove and the fourth fixing ring engages with the fifth fixing groove, the dust cover is detachably mounted on the mounting ring, so that the dust cover, the mounting ring, and the rainproof telescopic sleeve form a storage device that can accommodate the charging gun; at the same time, the adsorption fixing module is detachably mounted on the dust cover, so that the adsorption fixing module can limit the position of the rainproof telescopic sleeve.

[0019] Preferably, the rainproof telescopic sleeve is made of plastic. More preferably, the rain cover is made of rigid transparent plastic, and its side near the magnetic ring is integrally formed with the magnetic ring.

[0020] Preferably, the inner diameter of the first fixing groove opening is the same as the inner diameter of the second fixing groove opening; the outer diameter of the second fixing ring wall and the outer diameter of the third fixing ring wall are the same as the outer diameter of the first fixing ring wall. Here, "same" means completely equal or approximately the same, as long as it allows for proper mating between the fixing ring and the fixing groove. Of course, the fixing ring and the fixing groove can also be connected using an interference fit.

[0021] Preferably, the outer diameter is equal to the inner diameter. Preferably, the ring wall is provided with anti-slip texture.

[0022] Of course, a threaded connection can also be used between the retaining ring and the retaining groove. For example, the first retaining ring is threaded to the first retaining groove; the ring walls of the second retaining ring and the third retaining ring are threaded to the first retaining groove.

[0023] Since the inner diameter of the first fixing groove opening is the same as the inner diameter of the second fixing groove opening, and the outer diameters of the first fixing ring wall, the third fixing ring wall, and the second fixing ring wall are the same, users can assemble them according to their actual needs. For example, in low-temperature weather such as winter, there is no need to use the mounting ring; simply connect the rain cover and the rainproof telescopic sleeve and install them on the charging gun.

[0024] Of course, the dust cover can also be detachably connected to the side of the rainproof telescopic sleeve away from the rain cover, for example, by snap-fit ​​and slot connection, or by threaded connection.

[0025] Preferably, the rain cover is flared.

[0026] Preferably, the cavity of the mounting block includes a first opening communicating with the outside and a second opening penetrating the sidewall of the mounting ring, with the cooling fan located at the first opening.

[0027] Preferably, two mounting blocks are symmetrically arranged on the mounting ring.

[0028] Preferably, each of the two mounting blocks has a mounting plate at its bottom, and each mounting plate has a heat dissipation hole for accommodating a cooling fan. Each of the two mounting plates is fixedly connected to the two mounting blocks by a plurality of mounting bolts. Attached Figure Description

[0045] Charging guns for new energy vehicles (i.e., on-board charging guns) need to consider both storage and heat dissipation / waterproofing. Typically, for easy storage, a toolbox or storage device is provided for the charging gun, and for waterproofing, or rather, rainproofing, a separate waterproofing device is also included (as described in the background section). However, no existing device addresses heat dissipation during the charging process. Therefore, to solve these problems, existing technologies have implemented separate, independent devices for each issue. This not only increases the number of tools users need to carry in the vehicle, making storage more difficult, but also occupies trunk space and increases costs for the user.

[0046] In view of this, the present invention proposes a charging gun based on a modular design, which, in addition to the charging gun body 1, includes: a rain cover 5, a rainproof telescopic sleeve 4, a mounting ring 2 equipped with a cooling fan 11, a dust cover 14, and an adsorption fixing module 16. The rain cover 5 protects the charging gun head from rainwater during charging; the rainproof telescopic sleeve 4 serves both as a waterproof and dustproof component and as a storage component in conjunction with other parts; while the mounting ring 2 connects the rainproof telescopic sleeve 4 with other components, such as a heat shield, dustproof sleeve, and dustproof sleeve. The connection between any of the rain cover 5, dust cover 14, and adsorption fixing module 16 serves two purposes: firstly, to position the rainproof telescopic sleeve 4 (e.g., to prevent movement of the rainproof telescopic sleeve); and secondly, to work in conjunction with the rainproof telescopic sleeve 4 and other components for storage. The adsorption fixing module 16 acts as a reinforcement device during charging and also as a binding strap when storing the charging gun, keeping the rainproof telescopic sleeve 4 within a certain contracted state and preventing the charging gun's power cord from slipping out. Specifically, modular connections between components are achieved by using universal snap-fit ​​structures (e.g., fixing rings and fixing grooves) or threaded connections at the joints between components, allowing the rain cover 5, dust cover 14, and adsorption fixing module 16 to be connected to the mounting ring 2. Of course, in other embodiments, they can also be directly connected to the rainproof telescopic sleeve 4 via snap-fit ​​or threaded connections.

[0047] The following is a detailed description of the embodiments obtained by assembling the various components under different usage scenarios.

[0048] Example 1: Please refer to Figures 1-3 This utility model provides a waterproof charging gun, which includes a charging gun body 1, a rainproof telescopic sleeve 4 that can be fitted onto the charging gun body 1, and a rain cover 5 that is detachably connected to one side of the rainproof telescopic sleeve 4 to prevent rainwater from entering the car charging port. A magnetic ring 6 for adsorbing onto the car body is provided on the side of the rain cover 5 away from the rainproof telescopic sleeve 4.

[0049] In some embodiments, a second retaining ring 10 is provided on the side of the rain cover 5 near the rainproof telescopic sleeve 4, and a magnetic ring 6 for adsorbing onto the car body is fixedly connected to the side of the rain cover 5 away from the rainproof telescopic sleeve 4; correspondingly, a first retaining groove 8 is provided on the side of the rainproof telescopic sleeve 4 near the rainproof telescopic sleeve 4, and the rain cover 5 is snapped together by the second retaining ring 10 and the first retaining groove. Of course, in other embodiments, the rainproof telescopic sleeve 4 and the rain cover 5 may also be connected by a snap-fit ​​and slot, or by a threaded or other detachable connection method.

[0050] In practice, the rainproof telescopic sleeve 4 can be first fitted onto the charging gun 1, then the rain cover 5 can be connected to the front end of the rainproof telescopic sleeve 4, and finally the charging gun body 1 can be inserted into the charging port of the car. The magnetic ring 6 on the rain cover 5 can be attached to the car body, thus preventing rainwater from entering the charging gun body 1 and the car charging port, and preventing rainwater from damaging the charging gun body 1 and the car charging port.

[0051] In some embodiments, the charging gun further includes a mounting ring 2 for heat dissipation during charging. Specifically, one side of the mounting ring 2 is detachably connected to the rain cover 5, and the other side is detachably connected to the rainproof telescopic sleeve 4. That is, a mounting ring 2 is provided between the rain cover 5 and the rainproof telescopic sleeve 4, and at least one mounting block 3 is provided on the side wall of the mounting ring 2. The mounting block 3 has a cavity inside, and a cooling fan 11 for heat dissipation of the charging gun body 1 is provided in the cavity. It should be noted that a drive motor is connected to the cooling fan 11, and the cooling fan 11 is driven to rotate by the drive motor. The drive motor can be powered by a battery or directly by the charging gun body 1. The specific method needs to be selected according to actual needs. Battery power and direct power from the charging gun body 1 are both existing technologies and will not be elaborated on here.

[0052] In some embodiments, a second fixing groove 9 is provided on the side of the mounting ring 2 connected to the rain cover 5, and a first fixing ring 7 is provided on the side of the mounting ring 2 connected to the rainproof telescopic sleeve 4; the rain cover 5 is secured in the second fixing groove 9 by the second fixing ring 10; the mounting ring 2 is secured in the first fixing groove 8 of the rainproof telescopic sleeve 4 by the first fixing ring 7. In use, first, the rainproof telescopic sleeve 4 is fitted onto the charging gun body 1, then the mounting ring 2 is fitted onto the charging gun body 1, then the first fixing ring 7 on the mounting ring 2 is secured in the first fixing groove 8 on the rainproof telescopic sleeve 4, then the second fixing ring 10 on the rain cover 5 is secured in the second fixing groove 9 on the mounting ring 2, and finally the charging gun body 1 is inserted into the car's charging port. The magnetic ring 6 on the rain cover 5 is attracted to the car body, thus preventing rainwater from entering the charging gun body 1 and the car's charging port, preventing rainwater from damaging the charging gun body 1 and the car's charging port.

[0053] In some embodiments, two mounting blocks 3 are symmetrically arranged on the mounting ring 2, and each of the two mounting blocks 3 has a mounting plate 12 at its bottom. Each of the two mounting plates 12 has a heat dissipation hole for adapting to the cooling fan 11. The two mounting plates 12 are fixedly connected to the two mounting blocks 3 by a plurality of mounting bolts 13. By setting the mounting plates 12, the cooling fan 11 is fixed in the mounting block 3. The operator can use tools to loosen the mounting bolts 13 to remove the mounting plate 12 from the mounting block 3 for maintenance and repair of the cooling fan 11.

[0054] During use, most of the heat released by the charging gun body 1 during charging is retained inside the rain cover 5. At this time, the cooling fan 11 is driven to rotate, so that the cooling fan 11 quickly exhausts the heat generated by the charging gun body 1. The outside air then enters the rain cover 5 through the gap between the rainproof telescopic sleeve 4 and the charging gun body 1, realizing air cooling circulation, thereby preventing the charging gun body 1 from being damaged due to excessively high temperature for a long time.

[0055] Working principle: First, the rainproof telescopic sleeve 4 is fitted onto the charging gun body 1. Then, the mounting ring 2 is fixedly positioned on the charging gun body 1. Next, the first fixing ring 7 on the mounting ring 2 is snapped into the first fixing groove 8 on the rainproof telescopic sleeve 4. Then, the second fixing ring 10 on the rain cover 5 is snapped into the second fixing groove 9 on the mounting ring 2. Finally, the charging gun body 1 is inserted into the car's charging port, and the magnetic ring 6 on the rain cover 5 is attracted to the car body. The cooling fan 11 rotates, thereby exhausting the hot air generated by the charging gun to the outside. At the same time, it draws in the outside cold air from the opening of the rainproof telescopic sleeve 4 into the mounting ring 2, and even into the conductive rain cover 4. That is, the outside air enters the rain cover 5 from the gap between the rainproof telescopic sleeve 4 and the charging gun body 1, realizing air-cooling circulation.

[0056] In some embodiments, a slot can be provided inside the mounting ring 2 to cooperate with the protrusion 101 on the top of the charging gun, thereby limiting the mounting ring 2. Of course, in other embodiments, a flexible silicone ring (with multiple through holes on the silicone ring to connect the rainproof telescopic sleeve 4 to the inside of the mounting ring 2, so that cold air can enter from the opening of the rainproof telescopic sleeve under the action of the fan 11) can be provided on the inner wall of the mounting ring 2, which can be adapted to the shape of the charging gun body 1, thereby fixing or limiting the mounting ring 2. By limiting the mounting ring 2, it is possible to prevent the mounting ring 2 and the rainproof telescopic sleeve 4 from moving around when the user forgets to remove them. In fact, it is desirable for the user not to remove the mounting ring 2 and the rainproof telescopic sleeve 4, but only to remove the rain cover 5. This can provide daily protection for the charging gun, eliminate the need for separate storage, and also eliminate the need for reinstallation. Of course, the mounting ring 2 can also be equipped with a retaining ring or other structure that is compatible with the shape of the charging gun body 1. It is only necessary to ensure that the mounting ring 2 can be detachably installed on the charging gun body 1 and that the rainproof telescopic sleeve 4 is connected to the inside of the mounting ring 2 so that cold air can enter the mounting ring 2 and the rainproof cover 4.

[0057] In some other embodiments, a mounting ring may be provided, which differs from the mounting ring described above in that it is not equipped with a cooling fan, but with a battery for powering the cooling fan 11.

[0058] Example 2: Please refer to Figure 4 and Figure 5 This utility model also provides another charging gun, which includes the mounting ring and rainproof telescopic sleeve described in Embodiment 1 above, and further includes a dust cover 14. Specifically, the open end of the dust cover 14 is provided with a third fixing ring 15, which can be engaged with the first fixing groove 8 on the rainproof telescopic sleeve 4, or with the second fixing groove 9 on the mounting ring 2. For example, multiple protruding buckles are provided at intervals on the outer wall of the third fixing ring 15, and corresponding slots are provided on the first fixing groove 8 or the second fixing groove 9 accordingly. This is prior art and will not be described in detail here.

[0059] In some embodiments, the dust cover 14 includes a circular base plate 141 and an annular sidewall 142 connected to the base plate 141, wherein the third fixing ring 15 is provided on the side of the annular sidewall 142 away from the base plate 141.

[0060] Of course, in other embodiments, the third fixing ring 15 may also be threadedly connected to the first fixing groove 8 (or the second fixing groove 9).

[0061] In this embodiment, by providing the dust cover 14, the rain cover 5 can be directly removed from the mounting ring 2 when it is not needed. When the charging gun is not charging, in addition to removing the rain cover 5, the dust cover 14 can also be installed on the mounting ring 2 to protect the charging gun head. This prevents damage to the charging gun head from collisions during long-term idle periods and prevents dust or water from entering the charging gun head. Furthermore, since the rainproof telescopic sleeve 4 has a large diameter and a certain length (it also has a certain height even in the retracted state), it can also accommodate the charging gun's power cord, thus serving as a storage device in conjunction with the dust cover, eliminating the need for separate storage of the charging gun and the rainproof device.

[0062] Furthermore, to prevent the rainproof telescopic sleeve from expanding or contracting intermittently with vehicle movement or bumps when used as a storage device, and to prevent the wires stored inside the rainproof telescopic sleeve from running out due to the lack of a seal, a fifth fixing ring 17 can be provided on the side of the rainproof telescopic sleeve 4 away from the mounting ring 2. Multiple connecting ropes are provided circumferentially at intervals on the outer side of the ring wall of the fifth fixing ring 17, and multiple buckles are provided at the free ends of the connecting ropes. Correspondingly, multiple slots that can cooperate with the buckles are provided on the side of the rainproof telescopic sleeve 4 near the mounting ring 2 (for example, multiple slots are provided at intervals on the outer side of the slot wall of the first fixing slot 8). When the rainproof telescopic sleeve 4 is in the extended or retracted state and the buckles are engaged with the slots, the rainproof telescopic sleeve 4 is locked in the current extended or retracted state.

[0063] Of course, to accommodate charging cable reels of different lengths or thicknesses within the rainproof telescopic sleeve 4, the connecting rope is supported by an elastic material, allowing the length of the rainproof telescopic sleeve 4 to be adjusted as needed even when it is in a retracted state. Naturally, when the rainproof telescopic sleeve is in its naturally retracted state without external force, its length is the same as the length of the connecting rope in its natural state (i.e., its normal state without external force).

[0064] In this embodiment, a mounting ring 2 that can be fitted onto the charging gun body 1 is provided, and a rainproof telescopic sleeve 4 with a large diameter is provided on one side of the ring. A dust cover 14 is also provided. During charging, the cooling fan 11 on the mounting ring dissipates heat, thus protecting the charging gun from overheating. When not charging, the dust cover can be installed on the mounting ring to prevent dust from entering the charging head and to avoid damage to the exposed charging head caused by collisions during vehicle movement or bumpy rides. Furthermore, because the rainproof telescopic sleeve has a certain length (for example, in the retracted state, it covers the part of the charging gun head connected to the wire, and a small portion of the wire (e.g., 1 / 5 of the wire), while in the fully extended state, it covers the part of the charging gun head connected to the wire, and a portion of the wire (e.g., 3 / 5 of the wire)), the wire can be retracted into the rainproof telescopic sleeve, thus forming a storage device with the dust cover, mounting ring, and rainproof telescopic sleeve. Of course, the charging gun in this embodiment may also include the rain cover 4 as in embodiment 1.

[0065] Example 3: Please refer to Figure 6 and Figure 7 This utility model also provides another charging gun, which includes the mounting ring 2 and the rainproof telescopic sleeve 4 as described in Embodiment 1 or 2 above, and an adsorption fixing module 16 detachably mounted on the mounting ring 2 (or the rainproof telescopic sleeve 4). Specifically, the adsorption fixing module 16 includes a fourth fixing ring 162 and a plurality of suction cups 161, wherein each suction cup 161 is fixedly connected to the fourth fixing ring 162 via a connecting line 163.

[0066] To ensure the charging gun and charging port are locked together, a self-locking mechanism is installed on the charging gun to secure it to the charging port. However, existing self-locking mechanisms almost always involve a latch or hook on the top of the charging gun. Over time, the latch or hook on the charging gun may loosen due to wear and tear, especially under the weight of the charging gun itself. This can even cause the latch or hook to slightly disengage from the charging port's slot, resulting in slight loosening between the charging gun and the charging port during charging, or even downward tilting, leading to poor contact and affecting charging efficiency. Impacts or strong winds can also cause the charging gun to shake slightly, further affecting charging performance. Therefore, to mitigate this problem to some extent... To avoid this problem, an adsorption fixing module 16 is detachably installed on the mounting ring 2, which allows the charging gun to be fixed by a suction cup. On the one hand, the adsorption fixing module 16 distributes the weight of the charging gun to the vehicle body, reducing the impact on the buckle or hook and ensuring stability during the charging process. On the other hand, even in the event of a large collision or strong wind, the adsorption fixing module distributes some of the force to the car body, greatly reducing the probability that almost all the stress will be concentrated at the buckle or hook under the action of collision or wind, resulting in greater wear on the buckle or hook.

[0067] Preferably, the suction force of some suction cups 161 is greater than that of the other suction cups 161, so that when adsorption occurs, rotating the fourth fixing ring 162 causes the three suction cups 161 with greater suction force to be located on the top and sides of the charging gun, thus forming a stable triangular structure; of course, the other two, working together with the aforementioned three suction cups, can also weaken the impact force of wind or collision to a certain extent. Of course, more preferably, more suction cups can be added.

[0068] In other embodiments, the charging gun also includes the dust cover as described in Embodiment 2 above, and a third fixing groove can be provided on the side of the dust cover 14 away from the mounting ring 2. Correspondingly, the fourth fixing ring 162 of the adsorption fixing module 16 can be snapped into the third fixing groove of the dust cover 14, thereby eliminating the need for the buckles and slots on both sides of the rainproof telescopic sleeve 4 as described in Embodiment 2. Instead, when the dust cover 14 and the rainproof telescopic sleeve 4 are used as storage devices, the extension length of the rainproof telescopic sleeve 4 can be adjusted directly using the connecting wires 163 on the adsorption fixing module 16. For example, the connecting wires 163 can be attached to the rainproof telescopic sleeve 4 and tied together at the open end of the rainproof telescopic sleeve 4.
