Description

Technical Field

[0001] The utility model specifically relates to a charger protection box. Background Art

[0002] Transportation is an important hub for promoting social development. In today's society, with the gradual improvement of people's living standards, cars have become a necessity for every family. Now there are more and more cars on the road, and traffic jams are the norm. In order to travel conveniently, some people often choose electric vehicles. However, the electricity in electric vehicles will also be exhausted, and at this time, people need to charge the electric vehicles. If it rains, it will cause great trouble to people who need to charge their electric vehicles. Now some users have noticed such problems and created a protection device that can make the charger safely charge the electric vehicle in rainy days. For example, in the Chinese patent "CN202220844107.4", "A Multifunctional Rainproof Electric Vehicle Charging Protection Box" is disclosed. By setting a heat dissipation bottom shell and a rain cover, when users charge their electric vehicles in rainy days, they only need to open the rain cover, put the charger of the electric vehicle into the heat dissipation bottom shell, and then cover the rain cover to safely charge. However, the battery models assembled on different electric vehicles are different, and the charger models equipped are also different. If the model specifications of some chargers exceed the accommodation specifications of the protection box, users cannot safely charge in rainy days. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a charger protection box aiming at the deficiencies of the above-mentioned prior art.

[0004] To achieve the above object, the utility model provides the following technical solution: A charger protection box includes a housing assembly, and a wire part is arranged on the housing assembly. It is characterized in that: the housing assembly includes a first housing, a second housing, and a protection cover covered and connected to the upper end of the first housing. A connection port is arranged at the lower end of the first housing. The second housing is inserted into the first housing through the connection port and is cooperatively clamped with it. The second housing is axially movably arranged in the first housing.

[0005] With the above technical solution, by setting a first outer shell, a second outer shell, and a protective cover that is snap-connected to the upper end of the first outer shell, when the charger protection box is in the initial state, the second outer shell is inserted into the first outer shell. When the charger specification of the user meets the initial state specification of the charger protection box, the user can directly put the charger into the charger protection box, and the wire charges the battery vehicle through the wire part, avoiding the contact between rainwater and the charger when charging in rainy weather, thus preventing the charger from short-circuiting or leaking electricity, and playing a waterproof role. When the charger specification of the user is larger than the initial state specification of the charger protection box, the user can pull up the first outer shell to adjust the specification of the charger protection box and increase the internal space of the charger protection box. Then the user can put the charger into the charger protection box and then charge the battery vehicle through the wire part. Through this setting, the user can put chargers of different specifications into the charger protection box, increasing the versatility of the charger protection box and facilitating the popularization and application of the charger protection box. When the user does not use the charger protection box, the charger protection box can be restored to the initial state, which is convenient for users to carry and improves the practicality of the charger protection box.

[0006] The above-mentioned charger protection box can be further set as follows: Several groups of support bars are spaced on the outer peripheral surface of the second outer shell, and a first limiting part is extended inward from the connection port. The support bars are clamped and linked with the first limiting part, and the support bars control the moving distance of the first outer shell.

[0007] With the above technical solution, when the user chooses to charge outdoors, it is inevitable to encounter the action of wind, which may cause the charger protection box and the charger to collide and generate noise. At this time, the user controls the first outer shell to be pulled up and adjusts it to the specification that matches the charger. By setting several groups of support bars spaced on the outer peripheral surface of the second outer shell and a first limiting part extended inward from the connection port, and the support bars are clamped and linked with the first limiting part, the pulled-up position of the first outer shell can be fixed, preventing the first outer shell from shifting, and at this time the charger protection box fits the charger, reducing the generation of noise and improving the user experience.

[0008] The above-mentioned charger protection box can be further set as follows: A second limiting part is extended outward from the upper end of the second outer shell, and the second limiting part is correspondingly clamped with the first limiting part, and the second limiting part controls the farthest moving distance of the first outer shell.

[0009] With the above technical solution, when the user adjusts the charger protection box through the support bar, it is inevitable that the pulling force is too large, resulting in the separation of the first housing from the second housing. At this time, the user needs to reinstall the first housing on the second housing, which is very cumbersome. By setting the second limiting part, the second limiting part is correspondingly clamped with the first limiting part to control the farthest moving distance of the first outer shell. When the user pulls the first housing with a large pulling force, the first housing will not be separated from the second housing, further increasing the practicality of the charger protection box and improving the user experience.

[0010] The above-mentioned charger protection box can be further set as follows: The wire part includes a wire port, the wire port is arranged at the lower end of the second outer shell, and a heat dissipation port is arranged at the lower end of the second outer shell.

[0011] With the above technical solution, one end of the charger is the output terminal wire and the other end is the input terminal wire. When the user puts the charger into the charger protection box to charge the battery car, by setting the wire port at the lower end of the second housing, the output terminal wire of the charger can be connected to the battery car through the wire port, increasing the convenience of using the charger protection box, enhancing the user experience, and facilitating the popularization and application of the charger protection box; when using the charger to charge the battery car, since the charger is an electronic component, heat will be continuously generated during operation. The internal space of the charger protection box is relatively narrow, which is not conducive to heat dissipation, resulting in a rapid decline in the service life of the charger. By setting a heat dissipation port at the lower end of the second outer shell, the heat dissipation performance of the charger protection box is increased, and the attenuation of the service life of the charger when the charger is placed in the charger protection box for charging is reduced, further improving the user experience.

[0012] The above-mentioned charger protection box can be further set as follows: The wire part includes a first wire groove and a second wire groove. The first wire groove is arranged on the outer peripheral surface of the first outer shell, the second wire groove is arranged on the outer peripheral surface of the second outer shell, and the first wire groove and the second wire groove are correspondingly arranged.

[0013] With the above technical solution, one end of the charger is the output terminal wire and the other end is the input terminal wire. When the user puts the charger into the charger protection box to charge the battery car, by providing the first wire groove on the outer peripheral surface of the first outer shell and the second wire groove on the outer peripheral surface of the second outer shell, the input terminal wire of the charger can be connected to the power supply through the first wire groove and the second wire groove, increasing the convenience of using the charger protection box, enhancing the user experience, and facilitating the popularization and application of the charger protection box. At the same time, when the user uses the charger protection box, the wires provided on the charger are arranged more reasonably, increasing the aesthetic property.

[0014] The above-mentioned charger protection box can be further configured as follows: The charger protection box includes a rotating assembly, which includes a rotating shaft and a rotating buckle. The rotating shaft is arranged on the first outer shell, and the rotating buckle is arranged on the protection cover. The rotating buckle is rotatably installed on the rotating shaft to enable the protection cover to rotate and cover the first outer shell.

[0015] With the above technical solution, when the user closes the protection cover, the pressure applied is not up to the standard, resulting in an unstable connection relationship, so that the protection cover falls off or is lost. By setting the rotating assembly, the first outer shell and the protection cover are rotatably connected. In this way, regardless of whether the pressure received by the protection cover meets the standard or not, the protection cover can be stably connected to the first outer shell, avoiding the risk of the protection cover being lost and reducing the maintenance cost of the charger protection box; when the protection cover or the first shell is damaged, by setting the rotating assembly, the user can easily disassemble the first outer shell or the protection cover, and then replace the damaged first outer shell or protection cover to continue using, further reducing the maintenance cost of the charger protection box and facilitating the popularization and application of the charger protection box.

[0016] The above-mentioned charger protection box can be further configured as follows: The top end of the protection cover is provided with a hanging member; the upper end of the first outer shell extends outward to form a bayonet, and the lower end of the protection cover extends outward to form a plug. When the protection cover rotates and covers the first outer shell, the plug is inserted into the bayonet.

[0017] With the above technical solution, the precipitation during rainy days varies in amount, which is an uncontrollable factor by humans. Especially in the typhoon weather unique to the south, there is often a large amount of precipitation, resulting in water accumulation on the road surface. In such extremely bad weather, when the user needs to charge the battery vehicle, the charging position cannot be too close to the road surface. By providing a hanging member at the top end of the protection cover, the user can hang the charger protection box on the hook carried by the battery vehicle itself or at a high place for charging, increasing the practicality of the charger protection box; in typhoon weather, there is not only a large amount of precipitation but also strong winds, resulting in the charger placed in the charger protection box swaying and colliding with the wind, so that when the protection cover is closed and connected to the first outer shell, the connection relationship is unstable, resulting in the protection cover being opened and losing its waterproof function. By extending the upper end of the first outer shell outward to form a bayonet and the lower end of the protection cover outward to form a plug, this setting further strengthens the connection relationship between the protection cover and the first outer shell, improves the protection performance of the charger protection box, and enhances the user experience.

[0018] The above-mentioned charger protection box can be further configured as follows: A heat dissipation bracket is arranged at the bottom of the second outer shell, and the heat dissipation bracket extends into the second outer shell.

[0019] With the above technical solution, when used to charge an electric vehicle with a charger, since the charger is an electronic component, heat will be continuously generated during operation. The internal space of the charger protection box is relatively narrow, which is not conducive to heat dissipation. While increasing the heat dissipation performance of the charger protection box by setting heat dissipation openings, a heat dissipation bracket is provided at the bottom of the second outer shell to support the charger, increasing the space for the charger to dissipate heat and further improving the heat dissipation performance of the charger protection box; on rainy days, rain falls from a high altitude. When the rain hits the road surface during its fall, a parabola from top to bottom will be formed and splashed around. When the user puts the charger into the charger protection box to charge the electric vehicle and the charging position is close to the road surface, by setting the heat dissipation bracket, the distance between the charger and the road surface is increased, reducing the contact between the rain and the charger, improving the service life of the charger, enhancing the user experience, and facilitating the popularization and application of the charger protection box.

The second housing 2 is axially movable within the first housing 1.

[0029] By providing the first housing 1, the second housing 1, and the protection cover 3 that is hermetically connected to the upper end of the first housing 1, when the charger protection box is in the initial state, the second housing 2 is inserted into the first housing 1. When the user's charger specification conforms to the initial state specification of the charger protection box, the user can directly put the charger into the charger protection box, and the wire charges the battery vehicle through the wire part, avoiding the contact between rainwater and the charger during charging in rainy weather, thus preventing the charger from short-circuiting or leaking electricity, and playing a waterproof role; when the user's charger specification is larger than the initial state specification of the charger protection box, the user can pull up the first housing 1 to adjust the specification of the charger protection box and increase the internal space of the charger protection box. Then the user can put the charger into the charger protection box, and then charge the battery vehicle with the wire through the wire part; through this setting, the user can put chargers of different specifications into the charger protection box, increasing the versatility of the charger protection box, which is conducive to the popularization and application of the charger protection box; when the user does not use the charger protection box, the charger protection box can be restored to the initial state, which is convenient for users to carry and improves the practicability of the charger protection box.

[0033] When the user adjusts the charger protection box through the support bar 20, it is inevitable that the pulling force is too large, resulting in the separation of the first housing 1 from the second housing 2. At this time, the user needs to reinstall the first housing 1 on the second housing 2, which is very cumbersome. By setting the second limiting part 24, the second limiting part 24 is correspondingly clamped with the first limiting part 12 to control the farthest moving distance of the first outer shell 1. When the user pulls the first housing 1 with a large pulling force, the first housing 1 will not be separated from the second housing 2, further increasing the practicability of the charger protection box and improving the user experience.

[0034] The wire part includes a wire port 30, and the wire port 30 is arranged at the lower end of the second outer shell 2. A heat dissipation port 22 is arranged at the lower end of the second outer shell 2.

[0035] One end of the charger is the output terminal wire, and the other end is the input terminal wire. When the user puts the charger into the charger protection box to charge the battery car, by setting the wire port 30 at the lower end of the second housing 2, the output terminal wire of the charger can be connected to the battery car through the wire port 30, increasing the convenience of using the charger protection box and the user experience, which is beneficial to the popularization and application of the charger protection box; when using the charger to charge the battery car, since the charger is an electronic component, heat will be continuously generated during operation. And the internal space of the charger protection box is relatively narrow, which is not conducive to heat dissipation, resulting in a rapid decline in the service life of the charger. By setting the heat dissipation port 22 at the lower end of the second outer shell 2, the heat dissipation performance of the charger protection box is increased, and the attenuation of the service life of the charger when the charger is placed in the charger protection box for charging is reduced, further improving the user experience.

[0036] The wire part includes a first wire groove 31 and a second wire groove 32. The first wire groove 31 is arranged on the outer peripheral surface of the first outer shell 1, the second wire groove 32 is arranged on the outer peripheral surface of the second outer shell 2, and the first wire groove 31 and the second wire groove 32 are correspondingly arranged.

[0037] One end of the charger is the output terminal wire, and the other end is the input terminal wire. When the user puts the charger into the charger protection box to charge the battery car, by providing the first wire groove 31 on the outer peripheral surface of the first outer shell 1 and the second wire groove 32 on the outer peripheral surface of the second outer shell 2, the input terminal wire of the charger can be connected to the power supply through the first wire groove 31 and the second wire groove 32, increasing the convenience of using the charger protection box and the user experience, which is beneficial to the popularization and application of the charger protection box. At the same time, when the user uses the charger protection box, the wires provided on the charger are arranged more reasonably, increasing the aesthetics.

The rotating shaft 40 is arranged on the first outer shell 1, and the rotating buckle 41 is arranged on the protection cover 3. The rotating buckle 41 is rotatably installed on the rotating shaft 40, so that the protection cover 3 rotates and closes on the first outer shell 1.

[0039] When the user closes the protection cover 3, the pressure used does not meet the standard, resulting in an unstable connection relationship, so that the protection cover 3 falls off or is lost. By setting the rotating assembly, the first outer shell 1 and the protection cover 3 are rotatably connected. In this way, whether the pressure received by the protection cover 3 meets the standard or not, the protection cover 3 can be stably connected to the first outer shell 1, avoiding the risk of loss of the protection cover 3 and reducing the maintenance cost of the charger protection box; when the protection cover 3 or the first housing 1 is damaged, by setting the rotating assembly, the user can easily disassemble the first outer shell 1 or the protection cover 3, and then replace the damaged first outer shell 1 or protection cover 3 to continue using, further reducing the maintenance cost of the charger protection box, which is beneficial to the popularization and application of the charger protection box.
