Description

Technical Field

[0001] This utility model relates to the field of battery pack charging technology, and in particular to a split-type charging converter. Background Technology

[0002] like Figure 1 As shown, most lithium battery packs and chargers on the market are currently paired one-to-one, meaning one charger charges one battery pack. When a batch of battery packs need to be charged, either the corresponding number of chargers are used to charge each battery pack individually, or some battery packs are charged first, and after they are fully charged, the other battery packs need to be manually replaced for charging, and so on.

[0003] Clearly, the former requires a relatively large number of power interfaces and is limited by the usage environment, while the latter has low charging efficiency and requires more labor when dealing with a large number of battery packs to be charged.

[0004] Therefore, there is an urgent need for a separate charging converter to solve the above-mentioned technical problems. Utility Model Content

The first upper housing is fixed to the first lower housing. The first lower housing is provided with a plug-in hole and a first guide groove. The charger can be inserted into the plug-in hole along the first guide groove and connected to the metal clip assembly.

[0012] As a preferred technical solution of the above-mentioned split-type charging converter, the opposite side walls of the first guide groove form a first sliding groove on the side opposite to the first guide groove. The length direction of the first sliding groove is parallel to the guiding direction of the first guide groove. The charger is provided with a first slider, which can be slidably inserted into the first sliding groove.

[0013] As a preferred technical solution of the above-mentioned split-type charging converter, a first U-shaped groove is provided on one side wall of the first upper housing, and a second U-shaped groove is provided on one side wall of the first lower housing. One end of the input wire harness passes through the closed area of ​​the first U-shaped groove and the second U-shaped groove and is fixed by the first U-shaped groove and the second U-shaped groove.

[0014] As a preferred technical solution of the above-mentioned split-type charging converter, the second housing includes a second upper housing and a second lower housing, and the second upper housing and the second lower housing are fixedly connected by threaded fasteners.

[0015] As a preferred technical solution of the above-mentioned split-type charging converter, the connection position forms a second guide groove, and the battery pack can be connected to the metal insert assembly along the second guide groove.

[0016] As a preferred technical solution of the above-mentioned split-type charging converter, the plurality of the above-mentioned connection positions are arranged sequentially along the first direction, and the battery pack and the metal plug assembly are inserted along the second direction, wherein the first direction is perpendicular to the second direction.

[0017] As a preferred technical solution of the above-mentioned split-type charging converter, the plurality of the above-mentioned connection positions are arranged in a ring array around the second direction, and the battery pack and the metal plug assembly are inserted along the second direction.

[0018] As a preferred technical solution for the above-mentioned split-type charging converter, the metal clip assembly and the metal insert assembly are mounted on the circuit board.

[0019] As a preferred technical solution of the above-mentioned split-type charging converter, the metal clip assembly is connected to the input wire harness by welding.

[0020] And / or, the aforementioned metal insert assembly is connected to the aforementioned output harness by welding.

[0021] The beneficial effects of this utility model are:

[0022] This utility model provides a split-type charging converter, including an input unit, an output unit, and a circuit board. The input unit includes a first housing and metal clip assemblies, the metal clip assemblies being installed inside the first housing for electrical connection with a charger.

When one or more connection points are equipped with battery packs, the circuit board can transfer electrical energy to the corresponding battery packs through the output wiring harness for charging. By inserting the input unit into the charger, multiple battery packs can be charged simultaneously using a charger that previously only charged one-to-one. This not only achieves resource reuse and reduces production costs but also improves charging efficiency when multiple battery packs need charging. Furthermore, the separate design of the output and input units allows for more flexible arrangement and greater versatility. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0041] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0043] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0044] like Figures 2 to 8 As shown, this utility model provides a split-type charging converter 1, including an input unit 100, an output unit 200, and a circuit board 300. The input unit 100 includes a first housing 110 and a metal clip assembly 120, which is installed inside the first housing 110 for electrical connection with a charger 2. The output unit 200 includes a second housing 210 and multiple metal insert assemblies 220. The first housing 110 and the second housing 210 are relatively independent. The second housing 210 has multiple connection positions 211, and the metal insert assemblies 220 are installed inside the second housing 210. Each metal insert assembly 220 corresponds to one of the multiple connection positions 211 for electrical connection with a battery pack 3. The circuit board 300 is installed inside the second housing 210. The input unit 100 and the circuit board 300 are connected via an input wiring harness 310, and the metal insert assemblies 220 and the circuit board 300 are connected via an output wiring harness 320. The first housing 110 and the second housing 210 are connected via the input wiring harness 310.

[0045] In this way, electrical energy from the power supply can be sequentially transferred to the circuit board 300 through the charger 2, the metal clip assembly 120, and the input harness 310. When one or more connection points 211 are equipped with battery packs 3, the circuit board 300 can transfer electrical energy to the corresponding connection points 211 through the output harness 320 to charge the battery packs 3. When the input unit 100 is plugged into the charger, multiple battery packs 3 can be charged simultaneously using the charger 2, which originally charged each battery pack 3 one-to-one. This not only achieves resource reuse and reduces production costs but also improves charging efficiency when multiple battery packs 3 need charging. Furthermore, the separate design of the output unit 200 and the input unit 100 allows for more flexible arrangement and greater versatility.

[0046] Optionally, the first housing 110 includes a first upper housing 112 and a first lower housing 111. The first upper housing 112 is fixed to the first lower housing 111. The first lower housing 111 is provided with a plug hole 1111 and a first guide groove 1112. The charger 2 can be inserted into the plug hole 1111 along the first guide groove 1112 and connected to the metal clip assembly 120.

[0047] Specifically, the first upper housing 112 and the first lower housing 111 are fixed to form a first accommodating cavity. The metal clip assembly 120 is installed in the first accommodating cavity. The metal clip assembly 120 includes a clip seat and clips. The clip seat is fixed to the first upper housing 112 and / or the first lower housing 111. The clips are inserted into the clip seat. The clips are arranged in a one-to-one correspondence with the insertion holes 1111. The setting of the first guide groove 1112 facilitates the insertion of the output unit 200 and the charger 2, and simplifies the process of aligning the male connector of the charger 2 with the insertion holes 1111 and the clips.

[0048] Optionally, on the opposite side walls of the first guide groove 1112, a first sliding groove 1113 is formed on the side opposite to the first guide groove 1112. The length direction of the first sliding groove 1113 is parallel to the guiding direction of the first guide groove 1112. The charger 2 is correspondingly provided with a first slider, which can be slidably inserted into the first sliding groove 1113. In this way, through the sliding insertion relationship between the first sliding groove 1113 and the first slider, the assembly trajectory of the charger 2 and the input unit 100 can be standardized, and the movement of the input unit 100 relative to the charger 2 in directions other than the guiding direction of the first guide groove 1112 can be restricted.

[0049] Optionally, a first U-shaped groove 1121 is formed on one side wall of the first upper housing 112, and a second U-shaped groove 1114 is formed on one side wall of the first lower housing 111. One end of the input harness 310 passes through the closed area of ​​the first U-shaped groove 1121 and the second U-shaped groove 1114, and is fixed by the first U-shaped groove 1121 and the second U-shaped groove 1114. The input harness 310 is confined between the first upper housing 112 and the first lower housing 111, which can prevent the connection between the input harness 310 and the metal clip assembly 120 from becoming loose.

[0050] Optionally, the second housing 210 includes a second upper housing 212 and a second lower housing 213, with the second upper housing 212 and the second lower housing 213 being fixedly connected by threaded fasteners. This arrangement facilitates a detachable connection between the second lower housing 213 and the second upper housing 212.

[0051] Optionally, the first upper housing 112 and the first lower housing 111 are fixedly connected.

[0052] Optionally, the connection position 211 forms a second guide groove 2111, along which the battery pack 3 can be connected to the metal insert assembly 220. Thus, the second guide groove 2111 facilitates the connection between the output unit 200 and the battery pack 3, simplifying the alignment process between the female connector of the battery pack 3 and the male connector formed by the metal insert assembly 220.

[0053] The metal insert assembly 220 includes an insert holder and an insert. The insert holder is fixed to the second upper housing 212 and / or the second lower housing 213. One end of the insert is fixed to the insert holder, and the other end forms a male connector for insertion into the female connector of the battery pack 3.

[0054] Optionally, multiple connection points 211 are arranged sequentially along the first direction X, and the battery pack 3 is inserted into the metal insert assembly 220 along the second direction Y, with the first direction X and the second direction Y being perpendicular. In this way, when two adjacent connection points 211 are both equipped with battery packs 3, one battery pack 3 will not interfere with the assembly of the other battery pack 3 with the corresponding connection point 211.

[0055] Optionally, the multiple connection bits 211 can be arranged in a ring array around the second direction Y.

[0056] For example, the second housing 210 is square and includes a top wall, a bottom wall, and four peripheral side walls. Each of the four peripheral side walls can be provided with a connection position 211. In this way, when the battery pack 3 is connected to the output unit 200, the distribution of multiple battery packs 3 is more concentrated and occupies less space.

[0057] Optionally, the metal clip assembly 120 and the metal insert assembly 220 are mounted on the circuit board 300.

[0058] Optionally, the metal clip assembly 120 is connected to the input wiring harness 310 by welding; and / or, the metal insert assembly 220 is connected to the output wiring harness 320 by welding. This configuration simplifies the welding process and ensures a reliable connection.

[0059] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention.
