Description

Technical Field

[0001] The present application relates to the field of battery chargers, and in particular to a portable charger. Background Art

[0002] As more and more smart home appliances are introduced, rechargeable batteries are gradually favored by more consumers. Rechargeable batteries, also known as secondary batteries, can be used with a charger and can be recycled and charged anytime and anywhere. They have the advantages of being economical, environmentally friendly, and having sufficient power, and are widely used.

[0003] Among them, the charger used with the battery mainly includes a shell, a charging module and a pole piece. The shell has a receiving slot for the battery. The pole pieces are installed on both sides of the receiving slot and are used to contact the positive and negative poles of the battery. The charging module is arranged inside the shell and connected to the pole piece. It is used to convert alternating current into branch current and input it into the battery through the pole piece to realize the charging function.

[0004] However, current chargers are relatively large and inconvenient to carry when traveling, so further optimization and improvement are still needed. Utility Model Content

[0005] In order to improve the portability of the charger, the present application provides a portable charger.

[0006] The portable charger provided in this application adopts the following technical solution:

[0007] A portable charger includes a charger body, a charging module, and a pole piece. The charger body includes:

[0008] A main body, where the charging module is arranged;

[0009] and a telescopic portion, which is slidably arranged on the main body, wherein the pole pieces are respectively arranged on the main body and the telescopic portion and are used to contact the positive and negative poles of the battery, and the pole pieces are connected to the charging module. The telescopic portion and the main body include at least two states:

[0010] In the folded state, the telescopic portion slides and is accommodated inside the main body portion to shorten the overall length of the charger;

[0011] When in use, the telescopic portion is opened compared to the main body, and a charging cavity for placing the battery is formed between the telescopic portion and the main body. The length of the charging cavity is adapted to the length of the battery. When the battery is placed in the charging cavity, the two ends of the battery respectively abut the pole pieces.

[0012] By adopting the above technical solution, the telescopic part is first pulled outward compared to the main body, and by clamping the battery, the structural length requirement of the battery can be met, thereby realizing charging and discharging of the battery; in addition, under the telescopic action of the telescopic part, the charger can be telescoped and adjusted according to the actual carrying scenario. When the telescopic part slides to the inside of the main body, the overall length of the charger can be effectively shortened, the structure is more compact, and the portability of the charger is optimized and improved.

[0013] Preferably, the telescopic portion includes:

[0014] There are two telescopic slide rails, each parallel to the other, and two sides of the main body are provided with slide grooves for the two slide rails to slide;

[0015] and a support frame, which is located between the two telescopic slide rails and is respectively connected to the two telescopic slide rails, and the pole piece is arranged on the support frame.

[0016] By adopting the above technical solution, on the one hand, under the sliding guiding action of the telescopic slide rail and the slide groove, the telescopic part can be stably slid and set on the main body; on the other hand, the two telescopic slide rails and the support frame are equivalent to forming a frame structure, which has a good force effect, is not easy to deform, and has good structural stability.

[0017] Preferably, an elastic member is provided between the telescopic portion and the main body portion, and the elastic member is used to apply elastic force to make the telescopic portion slide toward the inside of the main body portion.

[0018] By adopting the above technical solution, the elastic member is equivalent to providing elastic force for the telescopic portion toward the inside of the main body. Such an arrangement enables the telescopic portion to clamp the battery under use conditions, making it difficult for the battery to loosen during charging.

[0019] Preferably, a limiting member is movably provided on the main body, and the telescopic part has a limiting groove for inserting the limiting member. When the limiting member is inserted into the limiting groove, the telescopic part is locked relative to the main body.

[0020] By adopting the above technical solution, when the limit member is inserted into the limit groove, the telescopic part can be suspended on the main body, preventing the telescopic part from suddenly rebounding after the battery is removed, thereby reducing the possibility of the telescopic part pinching the human body, making it safer and more reliable to use.

[0021] Preferably, there are a plurality of the limiting grooves, and the plurality of limiting grooves are sequentially spaced apart along the length direction of the telescopic portion.

[0022] By adopting the above technical solution, under the condition of setting multiple limit grooves, the telescopic part can stay at multiple positions on the main body to meet the charging needs of batteries of different lengths and sizes, and the structure is more flexible.

[0023] Preferably, the support frame includes a plurality of ridges arranged at intervals, and the ridges divide the interior of the support frame into a plurality of battery compartments.

[0024] By adopting the above technical solution, multiple battery compartments facilitate the placement and positioning of different batteries, making it easier and more convenient to use.

[0025] Preferably, heat dissipation holes are provided through the support frame.

[0026] By adopting the above technical solution, the battery usually generates heat during the charging process. At this time, by providing heat dissipation holes on the support frame, it is beneficial to dissipate heat from the battery being charged through the heat dissipation holes, so as to avoid heat accumulation in the battery and make charging safer.

[0027] Preferably, a pull ring is provided on one side of the telescopic portion.

[0028] By adopting the above technical solution, the pull ring is convenient for the user to operate and pull out the telescopic part, making it more convenient to use.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. By pulling the telescopic part outward and folding it inward relative to the main body, the battery can be clamped when the telescopic part is pulled out, meeting the structural space requirements of the battery and thus realizing battery charging and discharging. In addition, when in the telescopic state, the overall length of the charger can be effectively shortened, the structure is more compact, and the portability of the charger is optimized and improved.

[0031] 2. The elastic member can provide elastic force to the telescopic portion, so that the telescopic portion can clamp the battery under use conditions and the battery is not easy to loosen during charging;

[0032] 3. The heat dissipation holes can dissipate heat from the battery being charged to avoid heat accumulation in the battery and make charging safer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1-4 This application is described in further detail.

[0039] The embodiment of the present application discloses a portable charger.

[0040] Reference Figure 1 and Figure 2 The charger includes a charger body 1, a charging module (not shown in the figure) and a pole piece 2. The pole piece 2 and the charging module are respectively arranged on the charger body 1, and the charging module is connected to the pole piece 2. The charging module is used to convert AC power into DC power and charge the battery through the pole piece 2. The specific structure of the charging module is not described here.

[0041] Based on the above structural arrangement, in order to further reduce the structural volume of the charger and thereby improve the convenience of carrying the charger, in this embodiment, the charger body 1 includes a main body 11 and a telescopic portion 12. The main body 11 is mainly used to accommodate the charging module and is hollow inside. The charging module is installed inside the main body 11.

[0042] At the same time, the telescopic portion 12 is slidably arranged on the main body 11. At this time, the telescopic portion 12 can slide outward and fold inward compared to the main body 11. The number of pole pieces 2 is set to two, and the two pole pieces 2 are respectively installed on the main body 11 and the telescopic portion 12, and the two pole pieces 2 are arranged opposite to each other for contacting the positive and negative poles of the battery. At the same time, because the pole piece 2 is connected to the charging module, the battery can be charged through the charging module when it contacts the pole piece 2.

[0043] In summary, the telescopic portion 12 and the main body 11 include at least two states. Figure 1 One of the states is the folded state, in which the telescopic portion 12 slides and is accommodated inside the main body 11. At this time, the overall length of the charger is shortened, making it easy to carry outside.

[0044] Combine Figure 2The other is the state of charging the battery, which is defined as the use state. In the use state, the telescopic portion 12 slides outward compared to the main body 11, and then opens compared to the main body 11. At this time, a charging cavity for placing the battery is formed between the telescopic portion 12 and the main body 11. The length of the charging cavity can be adapted to the length of the battery, so that the battery can be placed in the charging cavity. At this time, the two ends of the battery are respectively in contact with the electrode 2 to achieve conduction to perform the charging function.

[0045] Continue to refer to Figure 2 In order to realize the reciprocating telescopic movement of the telescopic part 12, specifically, the telescopic part 12 includes a telescopic slide rail 121 and a support frame 122, wherein the telescopic slide rail 121 is a T-shaped slide rail structure, and the number thereof is set to two and they are arranged parallel to each other. At the same time, the support frame 122 is located between the two telescopic slide rails 121, and the support frame 122 is fixedly connected to the two slide rails respectively to form a stable frame support structure.

[0046] Furthermore, recessed grooves 111 are respectively provided on both sides of the main body 11, and the recessed contour of the grooves 111 is consistent with the telescopic slide rails 121. The two telescopic slide rails 121 are respectively installed at the two grooves 111, and the telescopic slide rails 121 and the surfaces of the grooves 111 abut against each other. At this time, the telescopic part 12 can slide compared to the main body 11 to realize telescopic and opening actions.

[0047] Furthermore, the function of the support frame 122 is mainly to support the battery so that the battery can be placed. Accordingly, in this embodiment, the support frame 122 is a plate-shaped structure, and the two sides of the support frame 122 are respectively connected to the two telescopic slide rails 121. In addition, a baffle is provided on the side of the support frame 122 away from the main body 11, in which one pole piece 2 is installed on the side of the main body 11 close to the telescopic part 12, and the other pole piece 2 is installed on the side surface opposite to the baffle and the main body 11, so that the pole piece 2 is provided on the support frame 122. At this time, the battery can be placed on the support plate and the two ends of the battery are respectively in contact with the pole piece 2 on the baffle and the pole piece 2 on the main body 11, so that the charging circuit is turned on.

[0048] Optionally, the support frame 122 also includes a plurality of ribs 1221 arranged at intervals. The specific number of the ribs 1221 can be adjusted according to the actual design, and can usually be one, three or five, etc. In this embodiment, three are used as an example. The length direction of the plurality of ribs 1221 is parallel to the length direction of the telescopic slide rail 121, and is integrally connected to the support frame 122. At this time, the plurality of ribs 1221 divides the interior of the support frame 122 into a plurality of battery compartments to accommodate a plurality of different batteries; accordingly, the number of relatively arranged pole pieces 2 should correspond to the number of battery compartments to achieve simultaneous charging of multiple batteries, making the charging action more efficient.

[0049] In addition, refer to Figure 3 In order to reduce the safety impact caused by the heat generated during battery charging, a heat dissipation hole 1222 is set through the plate part of the support frame 122. The heat dissipation hole 1222 is conducive to dissipating heat from the battery being charged through the heat dissipation hole 1222 to avoid heat accumulation in the battery and make charging safer.

[0050] In addition, in order to facilitate the opening and folding of the telescopic part 12, a pull ring 3 is fixedly installed on the side of the telescopic part 12 away from the main body 11. The pull ring 3 allows the user to operate the telescopic part 12 to pull out, making it more convenient to use.

[0051] Reference Figure 4 In order to further optimize the user experience of the charger, in this embodiment, an elastic member 4 is provided between the telescopic portion 12 and the main body 11. Specifically, a receiving groove for the elastic member 4 is opened inside the main body 11, and the receiving groove is arranged adjacent to the telescopic slide rail 121. The elastic member 4 adopts a spring structure and is placed in the receiving groove. At this time, the two ends of the elastic member 4 are fixedly connected to the main body 11 and the telescopic slide rail 121 respectively. At this time, the elastic member 4 can apply elastic force to the telescopic portion 12 to make the telescopic portion 12 slide toward the inside of the main body 11. When the elastic member 4 is in a natural state, the telescopic portion 12 is overlapped inside the main body 11.

[0052] Based on the above arrangement, the elastic member 4 provides elastic force to the telescopic portion 12 toward the interior of the main body 11. This arrangement enables the telescopic portion 12 to clamp the battery tightly under use conditions, preventing the battery from loosening during charging. It should be noted that to prevent the telescopic portion 12 from loosening relative to the main body 11, a first limiting protrusion 6 can be installed on the telescopic portion 12, and a second limiting protrusion 7 can be provided on the main body 11 to abut against the first limiting protrusion 6. The mutual abutment of the first limiting protrusion 6 and the second limiting protrusion 7 can prevent the telescopic portion 12 from loosening relative to the main body 11.

[0053] Further, look back Figure 2 In order to facilitate the convenient installation of the battery into the charger, in this embodiment, a limiting member 5 is movably provided on the main body 11, and a limiting groove 123 for inserting the limiting member 5 is provided on the telescopic portion 12. Specifically, the limiting groove 123 is located on the telescopic slide rail 121. When the limiting member 5 is inserted into the limiting groove 123, the telescopic portion 12 is locked compared to the main body 11, so that the telescopic portion 12 is suspended on the main body 11, preventing the telescopic portion 12 from suddenly rebounding after the battery is removed, thereby reducing the possibility of the telescopic portion 12 pinching the human body, making it safer and more reliable to use, and facilitating the installation of the battery.

[0054] Specifically, the limit member 5 adopts a screw structure in this embodiment, wherein a threaded hole is provided through the main body 11, one end of the threaded hole is connected to the slide groove 111, and the limit groove 123 can be opposite to the threaded hole; and one end of the screw has a knob block, and the screw is threadedly connected to the threaded hole. At this time, by rotating the screw, the screw can be extended into the slide groove 111 and inserted into the limit groove 123, thereby achieving a locking effect and being easy to use.

[0055] It is understandable that in other embodiments, a spring lock structure can be used instead of a screw structure, and any method of locking the telescopic slide rail 121 can be tried. No specific restrictions are made here. Regardless of the locking method adopted, it should be regarded as an alternative to this application.

[0056] Furthermore, different batteries have different lengths based on their models, so the telescopic length of the telescopic part 12 can be adjusted according to the size of different batteries. In order to enable the telescopic part 12 to stay in a suitable telescopic range, the number of limit grooves 123 can be set to multiple, such as two, three or four, etc., and there is no specific restriction here. At the same time, the multiple limit grooves 123 are arranged in sequence along the length direction of the telescopic part 12 to achieve multi-level stay of the telescopic part 12 on the main body 11 to meet the charging requirements of batteries of different lengths and sizes, and the structure is more flexible to use.

[0057] The implementation principle of a portable charger in an embodiment of the present application is as follows: under actual application conditions, the user can pull the telescopic part 12 to a suitable length according to the length of the battery, and then insert the limiting member 5 into the limiting groove 123 so that the telescopic part 12 can hover on the main body 11. At this time, the battery is placed in the corresponding battery compartment to realize the battery charging cycle; after the charging action is completed, the battery is taken out and the telescopic part 12 is loosened, and then, under the push of the elastic member 4, the telescopic part 12 slides into the main body 11 to achieve folding, the overall size of the charger is shortened, the structure is more compact, it is convenient to carry outside, and the convenience of use is improved.

[0058] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
