[0041] The charging gun of the new energy vehicle (i.e. the vehicle-mounted charging gun) needs to consider storage on one hand, and needs to consider heat dissipation and waterproof on the other hand. Usually, in order to facilitate storage, a tool box or a storage device is prepared for the charging gun, and in order to prevent water or rain, a waterproof device (such as the prior art recorded in the background art) is also provided for the charging gun. However, there is no existing device for heat dissipation during the charging process. Therefore, in order to solve the above problems, the prior art separately provides a corresponding independent device, which not only increases the tools carried by the user, but also increases the storage difficulty, occupies the trunk space of the vehicle, and increases the cost of the user.

[0042] Therefore, the utility model provides a charging gun based on modular design, which comprises a rain cover 5, a rainproof telescopic sleeve 4, a mounting ring 2 provided with a heat dissipation fan 11, a dust cover 14 and a suction fixing module 16 in addition to the charging gun body 1. The rain cover 5 is used to protect the gun head of the charging gun from rainwater during charging. The rainproof telescopic sleeve 4 plays a role in waterproofing and dustproofing and can be used in combination with other components to achieve storage. The mounting ring 2 connects the rainproof telescopic sleeve 4 with any of the rain cover 5, the dust cover 14 and the suction fixing module 16, and also plays a role in positioning the rainproof telescopic sleeve 4 (e.g. preventing the rainproof telescopic sleeve from moving), and can be used in combination with the rainproof telescopic sleeve 4 and other components to achieve storage. The suction fixing module 16 serves as a reinforcing device during charging and can also be used as a binding belt to keep or lock the rainproof telescopic sleeve 4 in a certain contracted state and prevent the charging gun cable from coming out. Specifically, the components are connected in a modular manner through general clamping structures (e.g. fixing rings and fixing grooves) or threaded connections at the interfaces between the components and other components, so that the rain cover 5, the dust cover 14 and the suction fixing module 16 can be connected to the mounting ring 2. Of course, in other embodiments, the rain cover 5, the dust cover 14 and the suction fixing module 16 can also be directly connected to the rainproof telescopic sleeve 4 through clamping or threaded connections.

[0043] The embodiments obtained by assembling the components under different use scenarios are described in detail below.

[0044] Embodiment 1: Please refer to Figures 1-3 The utility model provides a waterproof charging gun, which comprises a charging gun body 1, a rainproof telescopic sleeve 4 that can be sleeved on the charging gun body 1, and a rain cover 5 that can be detachably connected to one side of the rainproof telescopic sleeve 4 to prevent rainwater from entering the charging port of the vehicle. The side of the rain cover 5 away from the rainproof telescopic sleeve 4 is provided with a magnetic suction ring 6 for adsorbing on the vehicle shell.

[0045] In some embodiments, the rain cover 5 is provided with a second fixing ring 10 on the side close to the rainproof telescopic sleeve 4, and the rain cover 5 is fixedly connected with a magnetic suction ring 6 for being adsorbed on the automobile shell on the side away from the rainproof telescopic sleeve 4; correspondingly, the rainproof telescopic sleeve 4 is provided with a first fixing groove 8 on the side close to the rainproof telescopic sleeve 4, and the rain cover 5 is clamped by the second fixing ring 10 and the first fixing groove. Of course, in other embodiments, the rainproof telescopic sleeve 4 and the rain cover 5 can also be connected by a bayonet and a clamping groove, or a detachable connection mode such as a thread.

[0046] In specific implementation, the rainproof telescopic sleeve 4 is first sleeved on the charging gun 1, then the rain cover 5 is connected to the front end of the rainproof telescopic sleeve 4, and finally the charging gun body 1 is inserted into the charging port of the automobile, and the magnetic suction ring 6 on the rain cover 5 is adsorbed on the automobile shell, so as to block the rainwater from entering the charging gun body 1 and the automobile charging port, and prevent the rainwater from damaging the charging gun body 1 and the automobile charging port.

[0047] In other embodiments, in order to dissipate heat during charging, the charging gun further comprises a mounting ring 2. Specifically, one side of the mounting ring 2 is detachably connected with the rain cover 5, and the other side of the mounting ring 2 is detachably connected with the rainproof telescopic sleeve 4, that is, a mounting ring 2 is arranged between the rain cover 5 and the rainproof telescopic sleeve 4, and at least one mounting block 3 is arranged on the side wall of the mounting ring 2, and a cavity is formed in the mounting block 3, and a heat dissipation fan 11 for dissipating heat of the charging gun body 1 is arranged in the cavity. It should be noted that the heat dissipation fan 11 is connected with a driving motor, and the driving motor drives the heat dissipation fan 11 to rotate, and the driving motor is provided with electric energy. The electric energy can be provided by a storage battery, or directly provided by the charging gun body 1. The specific mode needs to be selected according to the actual needs. The modes of providing electric energy by the storage battery and directly by the charging gun body 1 are both prior art, and will not be described in detail here.

[0048] In some embodiments, the second fixing groove 9 is arranged on one side of the rainproof cover 5 connected with the mounting ring 2, and the first fixing ring 7 is arranged on one side of the rainproof telescopic sleeve 4 connected with the mounting ring 2; the rainproof cover 5 is clamped in the second fixing groove 9 through the second fixing ring 10; and the mounting ring 2 is clamped in the first fixing groove 8 of the rainproof telescopic sleeve 4 through the first fixing ring 7. In use, the rainproof telescopic sleeve 4 is first sleeved on the charging gun body 1, then the mounting ring 2 is sleeved on the charging gun body 1, then the first fixing ring 7 on the mounting ring 2 is clamped and fixed in the first fixing groove 8 on the rainproof telescopic sleeve 4, then the second fixing ring 10 on the rainproof cover 5 is clamped on the second fixing groove 9 on the mounting ring 2, and finally the charging gun body 1 is inserted into the charging port of the car, and the magnetic attraction ring 6 on the rainproof cover 5 is adsorbed on the car shell, so that rainwater is prevented from entering the charging gun body 1 and the charging port of the car, and damage to the charging gun body 1 and the charging port of the car caused by rainwater is prevented.

[0049] In some embodiments, two mounting blocks 3 are symmetrically arranged on the mounting ring 2, and the bottom of each of the two mounting blocks 3 is provided with a mounting plate 12, and the two mounting plates 12 are each provided with a heat dissipation hole for adapting the heat dissipation fan 11; and the two mounting plates 12 are respectively fixedly connected with the two mounting blocks 3 through a plurality of mounting bolts 13. By arranging the mounting plate 12, the heat dissipation fan 11 is fixed in the mounting block 3, and the worker can use a tool to rotate the mounting bolt 13 to dismount the mounting plate 12 from the mounting block 3, so as to maintain and repair the heat dissipation fan 11.

[0050] In use, most of the heat released by the charging gun body 1 during charging is retained in the rainproof cover 5, at which time the heat dissipation fan 11 is driven to rotate, so that the heat dissipation fan 11 quickly discharges the heat generated by the charging gun body 1, and the outside air enters the rainproof cover 5 from the gap between the rainproof telescopic sleeve 4 and the charging gun body 1, so as to realize air cooling circulation, thereby avoiding damage to the charging gun body 1 caused by long-time high temperature.

[0051] Working principle: first, the rainproof telescopic sleeve 4 is sleeved on the charging gun body 1, then the mounting ring 2 is fixed and limited on the charging gun body 1, then the first fixing ring 7 on the mounting ring 2 is clamped and fixed in the first fixing groove 8 on the rainproof telescopic sleeve 4, then the second fixing ring 10 on the rainproof cover 5 is clamped on the second fixing groove 9 on the mounting ring 2, and finally the charging gun body 1 is inserted into the charging port of the car, and the magnetic attraction ring 6 on the rainproof cover 5 is adsorbed on the car shell; the heat dissipation fan 11 rotates, thereby discharging the hot air generated by the charging gun to the outside, while sucking the cold air from the outside into the mounting ring 2 through the opening of the rainproof telescopic sleeve 4, and even into the conductive rainproof cover 4, that is, the outside air enters the rainproof cover 5 from the gap between the rainproof telescopic sleeve 4 and the charging gun body 1, so as to realize air cooling circulation.

[0052] In some embodiments, a clamping groove can also be arranged in the mounting ring 2 to cooperate with the protruding part 101 at the top of the charging gun, so as to limit the mounting ring 2. Of course, in other embodiments, a flexible silica gel ring (and a plurality of through holes are arranged on the silica gel ring to enable the rainproof telescopic sleeve 4 to be connected to the inside of the mounting ring 2, so that the cold air can enter from the opening of the rainproof telescopic sleeve under the action of the fan 11) can be arranged on the inner wall of the mounting ring 2, which can be adapted to the shape of the charging gun body 1, so as to realize the fixation or limitation of the mounting ring 2. By limiting the mounting ring 2, when the user forgets to remove the mounting ring 2 and the rainproof telescopic sleeve 4, the two will not run away. In fact, it is expected that the user does not remove the mounting ring 2 and the rainproof telescopic sleeve 4, but only removes the rain cover 5, which can protect the charging gun on a daily basis, does not need to be stored separately, and does not need to be reinstalled. Of course, a clamping ring or the like structure that is adapted to the shape of the charging gun body 1 can also be arranged in the mounting ring 2, which only needs to enable the mounting ring 2 to be detachably mounted on the charging gun body 1, and enable the rainproof telescopic sleeve 4 to be connected to the inside of the mounting ring 2, so that the cold air can enter the mounting ring 2 and the rain cover 4.

[0053] In other embodiments, a mounting ring can also be arranged, which is different from the above-mentioned mounting ring in that a battery for supplying power to the heat dissipation fan 11 is arranged on the mounting ring.

[0054] Embodiment 2: Please refer to Figure 4 and Figure 5 The utility model also provides another charging gun, which comprises the mounting ring and the rainproof telescopic sleeve in the above-mentioned embodiment 1 and further comprises a dust cover 14. Specifically, the opening end of the dust cover 14 is provided with a third fixing ring 15, which can be clamped with the first fixing groove 8 on the rainproof telescopic sleeve 4 or the second fixing groove 9 on the mounting ring 2. For example, a plurality of protruding buckles are arranged on the outer wall of the third fixing ring 15 at intervals, and correspondingly, a clamping groove is arranged on the first fixing groove 8 or the second fixing groove 9, which is not described here again as prior art.

[0055] In some embodiments, the dust cover 14 comprises a circular bottom plate 141 and an annular side wall 142 connected to the bottom plate 141, and the third fixing ring 15 is arranged on the side of the annular side wall 142 away from the bottom plate 141.

[0056] Of course, in other embodiments, the third fixing ring 15 and the first fixing groove 8 (or the second fixing groove 9) can also be threadedly connected.

[0057] In this embodiment, by setting the dust cover 14, when the rain cover 5 is not needed, the rain cover 5 can be directly removed from the mounting ring 2, and when the charging gun does not need to be charged, in addition to removing the rain cover 5, the dust cover 14 can also be installed on the mounting ring 2, thereby protecting the gun head of the charging gun, on the one hand, avoiding damage to the charging gun gun head caused by collision during long-term idle, on the other hand, preventing dust or splashed water from entering the charging gun gun head. And because the rain telescopic sleeve 4 has a larger diameter and a certain length (even in the contracted state it has a certain height), it can also accommodate the charging gun wire, that is, it is used as a storage device in cooperation with the dust cover, so that the charging gun and the rainproof device do not need to be stored separately.

[0058] Further, in order to prevent the rain telescopic sleeve from expanding or contracting from time to time when used as a storage device with the movement or jolt of the vehicle, and the wire stored in the rain telescopic sleeve all runs out due to no sealing, a fifth fixing ring 17 can also be provided on the side of the rain telescopic sleeve 4 away from the mounting ring 2, and a plurality of connecting ropes are provided on the outer side of the ring wall of the fifth fixing ring 17 in a circumferential direction, and the free ends of the connecting ropes are provided with a plurality of buckles, and correspondingly, the side of the rain telescopic sleeve 4 close to the mounting ring 2 is provided with a plurality of card slots that can cooperate with the buckles (for example, a plurality of card slots are provided on the outer side of the slot wall of the first fixing slot 8), when the rain telescopic sleeve 4 is in the expanded state or the contracted state, and the buckles are connected with the card slots, the rain telescopic sleeve 4 is locked in the current expanded or contracted state.

[0059] Of course, in order to adapt to different lengths or different thicknesses of the charging wire wound in the rain telescopic sleeve 4, the connecting rope is supported by an elastic material, so that the length of the rain telescopic sleeve 4 in the contracted state can also be adjusted according to actual needs. Of course, under the action of no external force, the length of the rain telescopic sleeve in the natural contracted state is the same as the length of the connecting rope in the natural state (i.e. the normal state under no external force).

[0060] In the embodiment, the mounting ring 2 is sleeved on the charging gun body 1, the rainproof telescopic sleeve 4 with a large pipe diameter is arranged on one side of the mounting ring 2, and the dust cover 14 is further provided. When charging, the heat dissipation fan 11 on the mounting ring can be used for heat dissipation, so that the charging gun is cooled. When not charging, the dust cover can be installed on the mounting ring to prevent dust from entering the gun head and avoid damage to the exposed gun head caused by collision during driving or bumping. In addition, the rainproof telescopic sleeve has a certain length (for example, in the contracted state, the rainproof telescopic sleeve covers the head of the charging gun, the part connected with the wire, and a small part of the wire (for example, 1 / 5 of the wire), and when the rainproof telescopic sleeve is in the fully stretched state, the rainproof telescopic sleeve can cover the head of the charging gun, the part connected with the wire, and a part of the wire (for example, 3 / 5 of the wire)), so that the wire can be stored in the rainproof telescopic sleeve, that is, the dust cover, the mounting ring and the rainproof telescopic sleeve form a storage device together. Of course, the charging gun of the embodiment can also include the rain cover 4 in the embodiment 1.

[0061] Embodiment 3: please refer to Figure 6 and Figure 7 The utility model also provides another charging gun, which comprises the mounting ring 2 and the rainproof telescopic sleeve 4 in the above-mentioned embodiments 1 or 2 and the adsorption fixing module 16 detachably installed on the mounting ring 2 (or the rainproof telescopic sleeve 4). Specifically, the adsorption fixing module 16 comprises 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 by a connecting wire 163.

[0062] In order to ensure the locking between the charging gun and the charging port, a self-locking mechanism is arranged on the charging gun to lock it in the charging port. However, the existing self-locking mechanism is almost a buckle or hook arranged on the top of the charging gun to lock. After long-term use, the locking mechanism between the hook or buckle on the charging gun and the charging port on the car may be loose due to long-term wear and tear, especially under the action of the gravity of the charging gun itself, or even the buckle or hook slightly detaches from the clamping groove of the charging port, so that the charging gun and the charging port are slightly loose during charging, and even the charging gun is inclined downward to cause poor contact and affect the charging effect. If there is a collision or strong wind, the charging gun will slightly sway, thereby affecting the charging effect, so as to avoid this problem to some extent. In order to avoid this problem, a suction fixing module 16 is detachably arranged on the mounting ring 2, so that the charging gun can be fixed by the suction cup. On the one hand, the suction fixing module 16 disperses the gravity of the charging gun itself to the car body, which affects the buckle or hook, to ensure the stability during charging. On the other hand, even if there is a larger collision or strong wind, the suction fixing module disperses part of the force to the car body, greatly reducing the probability that almost all stresses are concentrated on the buckle or hook to cause the buckle or hook to wear and tear greatly under the action of collision or wind.

[0063] Preferably, the suction force of part of the suction cups 161 is greater than that of the other suction cups 161, so that when suctioning, the three suction cups 161 with greater suction force are located at the top and both sides of the charging gun by rotating the fourth fixing ring 162, thereby forming a stable triangular structure; of course, the remaining two suction cups can also weaken the impact force to some extent in coordination with the aforementioned three suction cups. Of course, more suction cups can also be added.

[0064] In other embodiments, the charging gun also includes the dust cover in Embodiment 2, and the third fixing groove can be arranged on the side of the dust cover 14 away from the mounting ring 2. Correspondingly, the fourth fixing ring 162 of the suction fixing module 16 can be clamped in the third fixing groove of the dust cover 14, so that the buckle and the clamping groove in Embodiment 2 need not be arranged on both sides of the rainproof telescopic sleeve 4. When the dust cover 14 and the rainproof telescopic sleeve 4 are used as a storage device, the extension length of the rainproof telescopic sleeve 4 can be adjusted directly by using the connection lines 163 on the suction fixing module 16. For example, the connection lines 163 are attached to the rainproof telescopic sleeve 4 and tied together at the open end of the rainproof telescopic sleeve 4.

[0065] It is to be understood that the terminology "including", "comprising", or any other variation thereof, is intended to cover a non-exclusive inclusion such that processes, methods, articles, or apparatuses that comprise a list of elements are not necessarily limited to those elements, but can include other elements not expressly listed or inherent to such processes, methods, articles, or apparatuses.
