Description

Technical Field

[0001] The invention relates to the field of charger storage, and in particular to a battery vehicle charger which is convenient to store. Background Art

[0002] With the rapid growth in the number of electric vehicles, a common problem users face in daily use is the inconvenience of storing chargers. Traditional electric vehicle chargers are usually bulky in design, with long cables and a lack of effective organization and carrying solutions. This not only brings inconvenience to users when storing at home, carrying in the office, and traveling outdoors, but also easily causes damage to the charger or cable entanglement, affecting service life. Charging cables are usually designed with redundant lengths. If they are not properly organized after use, they are prone to cable entanglement and knotting, which is not only inconvenient to use, but may also cause damage to the cable sheath due to squeezing, affecting safety.

[0003] The currently disclosed Chinese patent CN212435384U discloses an electric vehicle charger, including a main body, a power connection line is arranged on one side outer surface of the main body, one end outer surface of the power connection line is fixedly connected to a charger shell, a power output line is fixedly installed on one side outer surface of the charger shell, a wire storage mechanism is arranged on the upper end outer surface of the charger shell, a convenient fixing mechanism is fixedly installed on the lower end outer surface of the charger shell, the wire storage mechanism includes a winding rod, a mounting seat, a limit plate and a wire fixing hole, and the lower end of the wire storage mechanism is fixedly installed with a convenient fixing mechanism. A mounting seat is provided on the outer surface of the end, a winding rod is provided on the upper outer surface of the mounting seat, the upper outer surface of the winding rod is fixedly connected to a limiting plate, wire fixing holes are provided on both sides of the limiting plate, the convenient fixing mechanism includes a silicone binding belt, an anti-wear block, an installation connecting sleeve and a silicone base, the lower outer surface of the convenient fixing mechanism is fixedly connected to the silicone binding belt, the upper outer surface of the silicone binding belt is fixedly connected to the silicone base, anti-wear blocks are provided on both sides of the lower end of the silicone base, and the upper outer surface of the silicone base is fixedly connected to the installation connecting sleeve.

[0004] According to the above patent, the above patent sets up a wire storage mechanism. Before the charger is used, the wires used in the charger can be wound around the winding rod through the winding rod set on the charger shell to prevent the wires from being entangled with each other and affecting the unfolding of the charger, which is beneficial to people's use. However, long wires may require more turns on the winding rod to be completely stored, which may cause the wires to be wound too tightly, which is not only time-consuming and laborious to untie, but may also cause physical damage to the cable material, such as excessive bending causing the insulation layer to rupture or the copper wire to deform. Therefore, there is a need for a battery vehicle charger that can be easily stored without damaging the wires. Summary of the invention

[0017] 1. The present invention adopts the design of the bundling mechanism so that the power connection line and the power output line can be respectively wound and fixed on both sides of the heat dissipation shell, thereby avoiding the entanglement between the cables. Compared with the traditional storage method of the elastically contracted power connection line and the power output line, it is convenient to organize the longer power connection line and the power output line, and to quickly unfold them when they are used next time. The charger body is placed in the heat dissipation shell and the storage shell, which can effectively protect the charger body from the influence of the external environment, prolong the service life of the charger body, and enable the charger body and its power connection line and the power output line to remain neat and orderly when not in use, which is convenient for users to use.

[0018] 2. The present invention adopts the guide groove design between the guide strip and the bonding plate so that the power connection line and the power output line can be respectively embedded and wound around the two sides of the heat dissipation shell, thereby avoiding entanglement between the cables and facilitating rapid unfolding the next time of use. At the same time, the design of the winding wheel further enhances the storage effect of the power connection line and the power output line, so that the power connection line and the power output line can be in a tightened state, thereby avoiding entanglement and knotting between the cables, improving the storage effect, and optimizing the user experience.

[0019] 3. The present invention can tightly clamp the power connection line and the power output line through the interlayer formed between the elastic clamping strip and the guide groove to ensure that they will not loosen or fall off during the storage process. The elastic design of the elastic clamping strip avoids hard squeezing of the power connection line and the power output line, reduces the risk of damage, and extends the service life. The arc-shaped edge design of the elastic clamping strip makes it easier for the power connection line and the power output line to slide into the interlayer, reducing the trouble of manually adjusting the storage position of the power connection line and the power output line, and improving the convenience of operation.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] See also Figure 1-Figure 8As shown, a battery vehicle charger that is convenient to store includes a charger body 1, and two ends of the charger body 1 are respectively provided with a power connection line 11 and a power output line 12. The charger also includes a storage shell 2 that can be taken on and put on the battery vehicle, and one end of the storage shell 2 has a detachable storage end cover 21. A heat dissipation shell 3 adapted to the charger body 1 is slidably provided in the storage shell 2, and one end of the heat dissipation shell 3 has a detachable heat dissipation end cover 31. The heat dissipation shell 3 is respectively provided with a power connection line 11 and a power output line 12. 2, two collecting mechanisms 4 are symmetrically arranged on both sides of the heat dissipation housing 3, and the collecting mechanisms 4 include a guide component 41 for winding the power connection line 11 or the power output line 12, and a clamping component 42 for fixing the power connection line 11 or the power output line 12. When the user arranges the power connection line 11 and the power output line 12 through the collecting mechanism 4, the power connection line 11 and the power output line 12 are respectively in a collecting state on one side of the heat dissipation housing 3, so that the power connection line 11 and the power output line 12 do not interfere with each other.

[0033] The surface of the heat dissipation housing 3 is provided with a plurality of heat dissipation holes 33, a heat dissipation gap 34 is formed between the heat dissipation housing 3 and the charger body 1, and openings for the power connection line 11 or the power output line 12 to pass through are provided on the closed end of the heat dissipation housing 3 and the heat dissipation end cover 31. When the charger body 1 is used for charging, the heat dissipation housing 3 can effectively dissipate heat for the charger body 1, protect the charger body 1, and prevent heat accumulation;

[0034] When the battery vehicle charger is used, the heat dissipation shell 3 is taken out from the storage shell 2, and then the power connection line 11 and the power output line 12 are removed from the corresponding bundling mechanism 4, so that the charging operation can be carried out. During the charging process, the heat dissipation shell 3 has a good heat dissipation effect on the charger body 1. On the contrary, when the battery vehicle charger is not in use, the power connection line 11 and the power output line 12 are first arranged through the corresponding bundling mechanism 4, and then the heat dissipation shell 3 is put back into the storage shell 2. The battery vehicle has a warehouse body for the storage shell 2 to be embedded. After the heat dissipation shell 3 is stored, the storage shell 2 is finally put back into the warehouse body of the battery vehicle, so as to facilitate the safe and orderly storage of the charger body 1, prevent the charger body 1 from being damaged by moisture or impact, and avoid the entanglement of the power connection line 11 and the power output line 12, which is convenient for next use.

[0035] Specific storage process: Before starting to store, make sure that the battery vehicle has completed charging, the power connection line 11 on the charger body 1 has been unplugged from the power socket, and the power output line 12 has also been disconnected from the battery vehicle, organize the power connection line 11, and wind the power connection line 11 around the guide component 41 on one side of the heat dissipation shell 3, and fix the power connection line 11 through the clamping component 42 to keep it neat and not loose, and also wind the power output line 12 around the guide component 41 on the other side of the heat dissipation shell 3, and fix it with the clamping component 42 to ensure that the two cables do not interfere with each other and are neat and orderly. After ensuring that all power lines on the heat dissipation shell 3 have been organized, push the organized heat dissipation shell 3 into the storage shell 2, and then install the storage end cover 21 to the open end of the storage shell 2 to ensure that it is closed to further protect the internal charger body 1 from the external environment. Finally, put the entire storage shell 2 into the specially designed compartment of the battery vehicle. The battery vehicle compartment is usually located under the seat or on the side of the vehicle body for users to quickly access.

[0036] See also Figure 2-Figure 8 and Fig.10 As shown, the guide assembly 41 includes a bonding plate 411 extending along the length direction of the heat dissipation shell 3, and guide bars 412 distributed on the bonding plate 411 at equal intervals along the height of the heat dissipation shell 3, and a guide groove for the power connection line 11 or the power output line 12 to be embedded therein is formed between each guide bar 412 and the bonding plate 411, and a storage area for the power connection line 11 or the power output line 12 to be wound multiple times is formed between several guide grooves.

[0037] In the process of arranging the power connection line 11 and the power output line 12, the power connection line 11 is embedded along the guide groove on the bonding plate 411 on one side of the heat dissipation shell 3. The guide groove formed between each guide bar 412 and the bonding plate 411 can accommodate the power connection line 11. The power connection line 11 is gradually wound in these guide grooves to form a multi-turn storage area to ensure that the power connection line 11 is neatly embedded in the guide groove without being loose or crossed. The power connection line 11 is fixed as a whole using the clamping assembly 42 to ensure that it will not fall off easily. Similarly, the power output line 12 is also fixed by the guide assembly 41 and the clamping assembly 42 on the other side to avoid entanglement between the cables and facilitate quick unfolding when used next time.

[0038] See also Figure 2-Figure 8As shown, the guide assembly 41 also includes a winding wheel 413 arranged at the end of the heat dissipation shell 3 or on the heat dissipation end cover 31, and the winding wheel 413 has a groove surrounding it. The winding wheel 413 is a support point for the power connection line 11 or the power output line 12 to be wound. When the user winds the power connection line 11 or the power output line 12 multiple times, the power connection line 11 or the power output line 12 is passed around the winding wheel 413 along the groove, so that the power connection line 11 or the power output line 12 can be in a tightened and contracted state.

[0039] In the process of arranging the power connection line 11 and the power output line 12, a winding wheel 413 arranged at the end of the heat dissipation shell 3 or the heat dissipation end cover 31 is used to pass the power connection line 11 along the groove on the winding wheel 413, so that the power connection line 11 is in a tightened and gathered state, and the power connection line 11 is continued to be wound until it is completely stored, and the clamping component 42 is used to fix the power connection line 11 to ensure that it will not fall off easily, and the power output line 12 is passed around the winding wheel 413 in the same way until the power output line 12 is tightened and then fixed by the clamping component, so that the power connection line 11 and the power output line 12 can be neatly arranged along the groove during the winding process, avoiding entanglement and knotting between the cables, and facilitating rapid unfolding when used next time. The existence of the winding wheel 413 also provides a support point, so that the power connection line 11 and the power output line 12 can remain in a tightened state during the winding process, reducing the looseness and clutter of the cables.

[0040] See also Figure 2-Figure 8 As shown, both ends of the bonding plate 411 have adaptive rubber pads 4111 for supporting the bent portion of the power connection line 11 or the power output line 12 during the bundling process.

[0041] When the power connection cable 11 and the power output cable 12 begin to be wound around the grooves on the winding wheel 413, they will contact the adaptive rubber pad 4111 at one of the two ends of the bonding plate 411 after each rotation of a certain angle. As the power connection cable 11 and the power output cable 12 are gradually tightened and continue to be wound, they will be supported by the adaptive rubber pad 4111 at each turning point. The adaptive rubber pad 4111 can automatically adjust its shape according to the pressure of the power connection cable 11 and the power output cable 12, thereby providing appropriate buffering and support for the power connection cable 11 and the power output cable 12 of different diameters and hardnesses. By reducing the chance of direct contact with hard surfaces, the adaptive rubber pad 4111 can effectively avoid wear on the outer skin of the power connection cable 11 and the power output cable 12.

[0042] See also Figure 2-Figure 8 and Fig.10As shown, the clamping assembly 42 includes an elastic clamping strip 421 extending along the edge direction of each guide strip 412, one side edge of the elastic clamping strip 421 is fixedly connected to the guide strip 412, and the other side edge of the elastic clamping strip 421 extends outward, and a sandwich 4211 is formed between the elastic clamping strip 421 and the guide groove, in which the power connection line 11 or the power output line 12 can be clamped.

[0043] When the power connection cable 11 and the power output cable 12 are placed in the guide groove, the elastic clamping strip 421 will naturally press on the power connection cable 11 and the power output cable 12, and the interlayer 4211 formed between the elastic clamping strip 421 and the guide groove can tightly clamp the power connection cable 11 and the power output cable 12 to ensure that they will not fall off or move easily, thereby ensuring the neatness and stability of the power connection cable 11 and the power output cable 12. Since the elastic clamping strip 421 has a certain degree of elasticity, the user can easily put in or take out the power connection cable 11 and the power output cable 12, while keeping the power connection cable 11 and the power output cable 12 in a tight state when needed.

[0044] See also Figure 2-Figure 8 and Fig.10 As shown, the outwardly extending edge of the elastic clip 421 is in an arc-shaped curved shape for conveniently guiding the power connection line 11 or the power output line 12 into the interlayer 4211 .

[0045] Since the other side edge of the elastic clip 421 is curved, when the power connection cable 11 and the power output cable 12 come into contact with the curved edge, they will naturally be guided into the interlayer 4211 between the elastic clip 421 and the guide groove. As the power connection cable 11 and the power output cable 12 are guided into the interlayer 4211, the elastic clip 421 will apply appropriate pressure to the power connection cable 11 and the power output cable 12, so that they are firmly fixed in the interlayer 4211, thereby reducing the trouble of manually adjusting the position of the power connection cable 11 and the power output cable 12 and improving the convenience of storage.

[0046] See also Figure 2-Figure 9 As shown, a sliding structure 5 is provided at each corner of the inner side of the storage shell 2, and a sliding frame is formed between all the sliding structures 5 for convenient placement and removal of the heat dissipation shell 3. The sliding structure 5 has an inner corner 51 fixedly set on the storage shell 2, and a ball 52 rotatably set on the inner corner 51 and capable of contacting the outer surface of the heat dissipation shell 3.

[0047] When the heat dissipation shell 3 contacts the sliding structure 5, the balls 52 on the sliding structure 5 will contact the outer surface of the heat dissipation shell 3. Since the balls 52 can rotate, they can reduce friction, making it easier for the heat dissipation shell 3 to slide into the storage shell 2. As the heat dissipation shell 3 is advanced, the sliding structures 5 at each corner work together to form a stable sliding frame, guiding the heat dissipation shell 3 to smoothly enter the storage shell 2. After the heat dissipation shell 3 completely enters the storage shell 2, it ensures that the charger body 1 is stored therein and will not be disturbed by external factors, thereby improving the service life of the charger body 1.

[0048] See also Figure 2-Figure 8 As shown, a baffle 22 is fixedly provided in the storage shell 2 and near its closed end for preventing the heat dissipation shell 3 from further penetrating, and pressing rods 211 are provided around the storage end cover 21 for pressing the heat dissipation shell 3 to a position in contact with the baffle 22. When the heat dissipation shell 3 is stored in place, a space is formed between the closed end of the storage shell 2 and the heat dissipation shell 3, and between the storage end cover 21 and the heat dissipation shell 3 to prevent the plug of the power connection line 11 or the power output line 12 from being squeezed.

[0049] When inserting the heat dissipation shell 3, align the heat dissipation shell 3 with the opening of the storage shell 2 and prepare to put it in. Use the sliding structure 5 at the inner corner of the storage shell 2 to guide the heat dissipation shell 3 to smoothly enter the interior of the storage shell 2. As the heat dissipation shell 3 is gradually pushed forward and the storage end cover 21 closes the opening of the storage shell 2, the pressing rod 211 will stably press the heat dissipation shell 3 at the position of the baffle 22 to prevent the heat dissipation shell 3 from swinging relative to the storage shell 2, so that it stays in the predetermined position, and the reserved space prevents the plugs of the power connection line 11 and the power output line 12 from being squeezed, avoiding the risk of damage.

[0050] See also Figure 2-Figure 6 As shown, a handle 23 is provided on the top of the storage shell 2 for users to lift conveniently, a base 24 is provided on the bottom of the storage shell 2 for convenient support, a magnetic attraction structure 25 is provided between the storage end cover 21 and the storage shell 2 for convenient disassembly of the storage end cover 21, and a handle 212 is also provided on the storage end cover 21 for users to remove it from the storage shell 2 conveniently.

[0051] When the storage end cover 21 closes the opening of the storage shell 2, the magnetic structure 25 will automatically adsorb the storage end cover 21 on the storage shell 2. When the storage shell 2 needs to be taken out from the compartment of the electric vehicle, the storage shell 2 can be conveniently lifted up by the handle 23 on the top. When the storage shell 2 needs to be placed on a certain surface, the bottom base 24 can provide stable support. If the storage end cover 21 needs to be removed, it can be easily pulled open by the handle 212 on the storage end cover 21, thereby improving the portability of storage and disassembly.

[0052] See also Figure 4-Figure 8 As shown, the open end of the heat dissipation shell 3 is provided with a clamping structure 32 for fixing the heat dissipation end cover 31, and the heat dissipation end cover 31 is fixedly provided with a compression spring 311 capable of resisting the charger body 1 on the side facing the charger body 1. When the clamping structure 32 fixes the heat dissipation end cover 31, the compression spring 311 presses the charger body 1 in a compressed state, and when the user manually releases the fixing state of the heat dissipation end cover 31 by the clamping structure 32, the compression spring 311 returns to a state without being acted upon by external force, so that the heat dissipation end cover 31 automatically pops out.

[0053] When the heat dissipation end cover 31 is fixed to the heat dissipation shell 3 by the snap-fit ​​structure 32, the compression spring 311 on the heat dissipation end cover 31 will press the charger body 1 to put it in a compressed state. Under normal use, the charger body 1 is protected in the heat dissipation shell 3, which provides a protective effect for the charger body 1 and facilitates the arrangement of the power connection line 11 and the power output line 12 through the bundling mechanism 4 on the heat dissipation shell 3, thereby facilitating the storage of the charger body 1 and improving the service life of the charger body 1. When the heat dissipation end cover 31 needs to be removed, the user manually releases the fixing state of the heat dissipation end cover 31 by the snap-fit ​​structure 32. Once the snap-fit ​​structure 32 is released, the compression spring 311 will return to a state without external force, pushing the heat dissipation end cover 31 to pop out automatically, so that the charger body 1 can be taken out for repair or replacement.

[0054] The present invention adopts the design of the bundling mechanism 4 so that the power connection line 11 and the power output line 12 can be respectively wound and fixed on both sides of the heat dissipation shell 3, thereby avoiding entanglement between cables. Compared with the traditional elastically shrinkable storage method of the power connection line 11 and the power output line 12, it is convenient to organize the longer power connection line 11 and the power output line 12, so as to facilitate rapid unfolding when used next time, and place the charger body 1 in the heat dissipation shell 3 and the storage shell 2, which can effectively protect the charger body 1 from the influence of the external environment, extend the service life of the charger body 1, and enable the charger body 1 and its power connection line 11 and the power output line 12 to remain neat and orderly when not in use, which is convenient for users to use.

[0055] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
