As one of the indispensable wiring harnesses on new energy commercial vehicles, the safety requirements of the charging seat with cable assembly are also constantly improving.

[0003] In the prior art, a charging cradle with a cable assembly is provided at one end for charging commercial vehicles. However, due to the structure of the charging port on the cradle, its protection level is only IP54, which means dustproofing is level 5: dust intrusion cannot be completely prevented, but the amount of dust that enters will not affect normal operation of the product; and waterproofing is level 4: protection against splashing water and water splashing from all directions. This level of protection is difficult to ensure the safety and service life of the charging cradle with cable assembly, so more effective protection is needed at the charging port end of the cradle. Summary of the Invention

[0004] The embodiment of the present application provides a waterproof electric vehicle charging port protection box to solve the problem of insufficient protection of the charging port end of the charging stand in the related art.

[0005] In order to achieve the above objectives, the present application provides a waterproof electric vehicle charging port protective box, and its technical solution includes: a protective box body, which is opened at both ends; a mounting plate, which is fixedly connected to the protective box body, and the charging seat is fixedly connected thereto; a flange, which extends outward from a port of the protective box body and forms an outward turn-over edge at the end, and a water guide groove is formed between the outward turn-over edge and the end of the protective box body, and the flange corresponds to the charging port of the charging seat; a door body, one side of which is hinged to the protective box body, and when closed, the flange is embedded in the door body.

[0006] In a more preferred improvement, in order to improve the sealing between the outer flange and the door body, a sealing member is provided between the end face of the outer flange and the door body for sealing the two.

[0007] In a more preferred improvement, in order to improve the sealing performance at the connection between the charging base and the mounting plate, a sealing gasket is provided at the connection between the mounting plate and the charging base to seal the two.

[0008] In a more preferred improvement, in order to make the sealing between the mounting plate and the inner wall of the protection box body stronger, the outer edge of the mounting plate and the inner wall of the protection box body are sealed.

[0009] In a more preferred improvement, in order to minimize the entry of external water into the protective box body, a protective plate is fixedly connected to the other open end of the protective box body, and a threading hole for passing the charging seat cable is provided at a position corresponding to the end of the charging seat.

[0010] In a more preferred improvement, in order to seal between the charging base and the protective plate, a sealing sleeve is fixedly connected to the protective plate at the position corresponding to the threading hole and is sleeved on the charging base; a sealing ring is provided between the sealing sleeve and the charging base for sealing the two.

[0011] In a more preferred improvement, in order to drain the accumulated water in the sealing sleeve in time, the bottom of the sealing sleeve is connected with a water pipe, and one end of the water pipe away from the sealing sleeve is connected to the bottom of the protective box body.

[0012] In a more preferred improvement, in order to allow a small amount of water that enters the protective box body to be discharged in time, a drainage hole is opened at the bottom of the protective box body, and the drainage hole is located between the mounting plate and the protective plate.

[0015] The beneficial effects of the technical solution provided by this application include:

[0016] An embodiment of the present application provides a waterproof electric vehicle charging port protective box. After the user installs the door body on the protective box body, a sealed cavity is formed between the door body, the protective box body and the mounting plate; because the flange is embedded in the door body, the end of the door body is located between the water guide grooves. When external water splashes into the gap between the door body and the end of the protective box body, most of the water flows downward from the water guide groove; in addition, the outer flange is formed by extending outward from the port of the protective box body, so the outer flange also has a certain water-blocking performance, further reducing the water entering the sealed cavity; in summary, the electric vehicle charging port protective box greatly blocks external water from entering the sealed cavity, so that the charging port of the charging seat is more effectively protected, reduces the damage to the charging port caused by improper protection during use, and extends the service life of the charging seat and cable assembly.

DETAILED DESCRIPTION

[0024] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] In the existing technology, the charging seat with cable assembly is one of the indispensable wiring harnesses on new energy commercial vehicles, and its safety needs to be guaranteed. During use, a charging seat for charging the commercial vehicle is provided at one end. However, due to the structure of the charging port of the charging seat, its own protection level can only reach IP54 (that is, dustproof level 5: cannot completely prevent dust intrusion, but the amount of dust intrusion will not affect the normal operation of the product; waterproof level 4: prevent splashing water intrusion, prevent splashing water from all directions). This protection level is difficult to ensure the safety of the charging seat with cable assembly and its service life.

[0026] In order to solve the above problems, an embodiment of the present application provides an embodiment of a waterproof electric vehicle charging port protection box, which can solve the problem of insufficient protection of the charging port end of the charging stand, thereby making the charging stand with cable assembly safer when in use.

[0027] Reference Figure 1 A waterproof electric vehicle charging port protective box includes a protective box body 1, a mounting plate 2, a flange 3 and a door body 4; both ends of the protective box body 1 are opened, the mounting plate 2 is fixedly connected to the protective box body, and the charging seat is fixedly connected thereto; the flange 3 is fixedly connected to one end of the opening of the protective box body 1 and corresponds to the charging port of the charging seat; one side of the door body 4 is hinged to the protective box body 1, and when the door body 4 is closed, the flange 3 is embedded in the door body 4.

[0028] Specifically, combined with Figure 1 and Figure 2 The protective box body 1 is a rectangular parallelepiped as a whole, with openings at both ends along its width direction; the mounting plate 2 is a rectangular plate as a whole. In order to facilitate the connection between the mounting plate 2 and the protective box body 1, the mounting plate 2 is folded around, and the four folded edges of the mounting plate 2 are respectively fitted with the four surfaces of the inner wall of the protective box body 1; in the embodiment of the present application, the mounting plate 2 has two mounting holes 21 for installing the charging seat at intervals along the length direction of the protective box body 1, that is, two charging seats are installed on the mounting plate 2 in the embodiment of the present application.

[0029] The structure of flange 3 is as follows Figure 1 and Figure 2 As shown, the flange 3 is formed by extending outward from one end of the protective box body 1, and the cross-section of one side of the flange 3 along the horizontal direction is "L"-shaped, which includes a connecting ring 31 and an outer flange 32; the connecting ring 31 is fixedly connected to the port of the protective box body 1 and surrounds the port of the protective box body 1, and the outer flange 32 is fixedly connected to the end of the connecting ring 31 and the two are formed as one piece, the outer contour edge of the outer flange 32 is larger than the opening contour of the protective box body 1, and a water guide groove 33 is formed between the outer flange 32 and the end of the protective box body 1.

[0030] Combine Figure 1 and Figure 2A circular folded edge is provided on the side of the door body 4 close to the protective box body 1, so that a cavity is formed on the side of the door body 4 close to the protective box body 1. When the user closes the door body 4, the flange 3 extends into the cavity, and the end face of the circular folded edge is located between the flange 3 and the end of the protective box body 1.

[0031] In the examples of this application, refer to Figure 1 The hinged side of the door body 4 is provided with a hinge 41, and the door body 4 and the protective box body 1 are hinged by the hinge 41, and the direction of the hinge axis is parallel to the height direction of the protective box body 1. One side of the hinge 41 is fixedly connected to the door body 4, and the other side is fixedly connected to the protective box body 1; the door body 4 is provided with a locking member 5 on one side relative to the hinge 41 to lock the side. Specifically, in the embodiment of the present application, the locking member 5 is a door lock 51, and the door lock 51 itself has a waterproof function to prevent external water from passing through the door lock. 51 enters the protective box body 1; the door lock 51 is installed on the door body 4, and the lock tongue of the door lock 51 is detachably connected to the protective box body 1; when the user needs to close the door body 4, the door lock 51 is turned to make the lock tongue connected to the protective box body 1, and when the user needs to open the door body 4, the door lock 51 is turned to separate the lock tongue and the protective box body 1, and the door body 4 can be opened; this arrangement is convenient for the user to open and close the door body 4, and also enables the door body 4 to be closed more stably during the driving of the vehicle.

[0032] In other embodiments, the locking member 5 can also be a hasp lock; the first lock seat of the hasp lock is fixedly connected to the door body 4, and the second lock seat of the hasp lock is fixedly connected to the position of the protective box body 1 corresponding to the first lock seat, and the first lock seat can be detachably connected to the second lock seat; when the first lock seat and the second lock seat are separated, the door body 4 can be opened, and when the first lock seat and the second lock seat are connected together, the door body 4 is closed.

[0033] In addition, the locking member 5 can also be implemented with other commonly used locking structures, such as side-release buckles, etc., which are no longer listed one by one in this application.

[0034] When the user turns the door lock 51 to lock the door body 4 on the protective box body 1, a sealed cavity is formed between the door body 4, the protective box body 1 and the mounting plate 2; since the flange 3 is embedded in the door body 4, the end of the door body 4 is located between the outer flange 32 and the guide groove at the end of the protective box body 1. When external water splashes into the gap between the door body 4 and the end of the protective box body 1, most of the water flows downward from the guide groove; in addition, since the outer flange 32 of the flange 3 is larger than the outline of the opening of the protective box body 1, the outer flange 32 also has a certain water-blocking performance, which further reduces the entry of water into the sealed cavity; the combination of the door body 4 and the flange 3 forms the first line of protection for the sealed cavity, which greatly blocks external water from entering the sealed cavity, so that the charging port of the charging base is better protected.

[0035] Although the combination of flange 3 and door body 4 better protects the charging port of the charging stand, in actual use, due to the strong impact of external water, some water will enter the sealed cavity from the gap between the door body 4 and the outer flange 32. Figure 1 and Figure 2 , a sealing member 6 for sealing the two is provided between the end face of the outer flange 32 and the door body 4; specifically, the sealing member 6 can be a sealing strip 61 or a sealing plate. The present application adopts a sealing strip 61, which is made of rubber or silicone material. The sealing strip 61 is fixedly connected to the door body 4 by bonding. When the door body 4 is closed, the sealing strip 61 is attached to the end face of the outer flange 32; at the same time, it should be noted that the end face of the outer flange 32 needs to be polished to a certain extent so that the sealing strip 61 can be better attached to the end face of the outer flange 32 to improve the sealing effect; when the user uses the door lock 51 to lock the door body 4 on the protective box body 1, the door body 4 will generate a certain pressure on the sealing strip 61, so that the sealing strip 61 has a certain amount of compression, thereby ensuring the reliability of the seal between the door body 4 and the outer flange 32.

[0036] A sealing strip 61 is provided between the door body 4 and the outer flange 32, which further enhances the sealing performance of the sealed cavity and becomes a second line of protection for the sealed cavity.

[0037] Through the above settings, the waterproof problem on the side of the mounting plate 2 close to the charging port of the charging base is solved, but it is not difficult to find that the waterproof problem on the other side of the mounting plate 2 still needs to be solved, and water splashed from the end of the charging base may still enter the sealed cavity.

[0038] After analysis, first of all, the sealing between the four folded edges of the mounting plate 2 and the inner wall of the protective box body 1 needs to be ensured. In this application, glue is applied at the position where the mounting plate 2 and the inner wall of the protective box body 1 are connected, thereby filling the gap between the mounting plate 2 and the inner wall of the protective box body 1, completing the sealed connection between the mounting plate 2 and the protective box body 1, and effectively preventing water splashing from the end of the charging stand from entering the sealed cavity through the gap between the mounting plate 2 and the protective box body 1, forming a third line of protection for the sealed cavity.

[0039] In other embodiments, the mounting plate 2 and the protective box body 1 can also be integrally formed to ensure the sealed connection between the mounting plate 2 and the protective box body 1 to the greatest extent. However, compared with the preferred embodiment of this application, the processing cost of this method will be relatively higher.

[0040] In addition to the sealing defects between the mounting plate 2 and the inner wall of the protective box body 1, there are still some gaps at the connection between the mounting plate 2 and the charging base, which may cause external water to enter the sealed cavity through the gap. Figure 2 and Figure 3 A sealing gasket 7 is provided at the connection between the mounting plate 2 and the charging base to seal the two. Under the sealing action of the sealing gasket 7, the sealing performance of the connection position between the mounting plate 2 and the charging base is enhanced, forming the fourth line of protection of the sealed cavity.

[0041] After the above settings, the sealed cavity has undergone four layers of protection, which effectively protects the charging port of the charging station. However, during use, the inventor found that since the protective box body 1 is exposed to the outside when in use, when there is a lot of water outside, more water will impact the side of the protective box body 1 close to the end of the charging station. Over time, the third and fourth layers of protection will be damaged to a certain extent, reducing the protective effect of the protective box on the charging port of the charging station. In order to minimize the amount of water entering the protective box body 1, refer to Figure 2 The protective box body 1 is fixedly connected to the open end away from the door body 4 with a protective plate 8, and the four sides of the protective plate 8 are also folded. The edge of the protective plate 8 and the inner wall of the protective box body 1 are also sealed, and the gap between the two is filled with glue; the protective plate 8 is provided with a threading hole 81 at the position corresponding to the end of the charging seat, and the threading hole 81 corresponds to the mounting hole 21. The charging seat with cable assembly passes through the threading hole 81, and the outer diameter of the threading hole 81 is slightly larger than the requirement for the charging seat with cable assembly to pass through.

[0042] By setting up the protective plate 8, the water from the outside is blocked, so that as little water as possible enters the protective box body 1, or even if water enters the protective box body 1, the impact force of the water flow entering the protective box body 1 is greatly reduced, and the impact of water on the third and fourth lines of protection is reduced, thereby forming the fifth line of protection of the sealed cavity, which further enhances the reliability of the protection of the protective box.

[0043] After setting up the above five protections, the user found in the process of using the protective box that even if the threading hole 81 is as small as possible, a small amount of water will still enter the protective box body 1 from the gap between the threading hole 81 and the charging seat cable assembly; however, there are multiple charging seat cable assemblies led out from the end of the charging seat, and there will be a certain gap between each charging seat cable assembly, and there will also be a certain gap between the charging seat cable assembly and the threading hole 81. Therefore, it is inconvenient to seal between the charging seat cable assembly and the threading hole 81. The inventor tried to use heat shrink tube sealing and found that the sealing effect was not very good. After filling the space between the charging seat cable assembly and the threading hole 81 with sealant, although the sealing can be guaranteed to a certain extent, it is not conducive to later maintenance. Later analysis showed that the protection level of the end of the charging seat can reach IP67, which can meet the safe use of the charging seat cable assembly, so the sealing position was moved from the charging seat cable assembly. Finally, it was found that sealing the side wall of the charging seat can achieve a good sealing effect.

[0044] Specifically, refer to Figure 2 , a sealing sleeve 9 is fixedly connected to the protective plate 8 at the position corresponding to the threading hole 81, the sealing sleeve 9 faces the mounting plate 2, the end of the charging seat extends into the sealing sleeve 9, and the charging seat cable assembly passes through the sealing sleeve 9; a sealing ring 91 for sealing the two is provided between the sealing sleeve 9 and the charging seat, and the sealing ring 91 is an O-ring, and a snap-in groove 92 is opened on the sealing sleeve 9, the O-ring is snapped on the snap-in groove 92, and the side wall of the charging seat squeezes the inner ring of the O-ring; through the above embodiment, the water entering from the gap between the charging seat cable assembly and the threading hole 81 enters the sealing sleeve 9, and is blocked in the sealing sleeve 9 after passing through the O-ring barrier, and after the car is running, most of the water blocked in the sealing sleeve 9 is thrown out, which greatly reduces the probability of water seeping into the protective box body 1 from the sealing ring 91, forming the sixth line of protection for the sealed cavity.

[0045] In addition, refer to Figure 2 After the sealing sleeve 9 and the end of the charging seat are matched, the end of the charging seat is supported. Since the charging port end of the charging seat and the mounting plate 2 are connected, after the mounting plate 2 and the sealing sleeve 9 are matched, both ends of the charging seat are supported, which improves the stability of the connection between the charging seat and the protective box body 1, so that the charging seat can be more firmly connected to the protective box body 1 when it is pulled by the charging seat cable assembly.

[0046] During the driving of the car, although most of the water in the sealing sleeve 9 will be thrown out of the sealing sleeve 9, a small amount of water will still remain in the sealing sleeve 9, leaving the trouble of subsequent water seepage. In order to solve this problem, refer to Figure 4 A water pipe 93 is connected to the bottom of the sealing sleeve 9, and one end of the water pipe 93 away from the sealing sleeve 9 is connected to the bottom of the protective box body 1; when external water enters the sealing sleeve 9, the water in the sealing sleeve 9 is thrown out by the vehicle on the one hand, and flows out of the protective box body 1 through the water pipe 93 on the other hand, so that the water in the sealing sleeve 9 is discharged more promptly and thoroughly, further enhancing the effect of the sixth line of protection.

[0047] After a period of use, users found that even with the sixth protection, a small amount of water would still enter the protective box body 1 from between the O-ring and the side wall of the charging base. If not handled in time, the water between the mounting plate 2 and the protective plate 8 would accumulate more and more, thereby soaking the mounting plate 2 and causing the risk of water seepage into the sealed cavity. Therefore, referring to Figure 2 A plurality of drainage holes 11 are provided at the bottom of the protective box body 1. The drainage holes 11 are located between the mounting plate 2 and the protective plate 8. Water seepage between the mounting plate 2 and the protective plate 8 can be discharged in time from the plurality of drainage holes 11, thereby further enhancing the overall waterproof effect of the protective box.

[0048] The working principle of the embodiment of the present application: When the user uses the electric vehicle charging port protection box to protect the charging port of the charging seat, the user first installs the charging seat on the mounting plate 2, the end of the charging seat extends into the sealing sleeve 9, and the charging seat cable assembly passes through the sealing sleeve 9, and then the door body 4 is closed and locked with the door lock 51. The electric vehicle charging port protection box forms six layers of protection for the charging port of the charging seat, so that the charging port of the charging seat can be more effectively protected, reducing the damage caused by improper protection during use of the charging port, and extending the service life of the charging seat cable assembly.
