Summary of the utility model

[0005] The purpose of this application is to provide an adapter housing and a battery pack adapter, which can not only eliminate the mating gaps on the surface of the protective housing but also effectively improve the structural strength of the protective housing.

[0006] The embodiments of this application are implemented as follows:

[0012] As an alternative embodiment, a second connecting member connected to the top cover portion is installed on the adapter control board; there are multiple second connecting members and they are arranged at intervals along the circumferential direction of the adapter control board.

[0013] As an alternative embodiment, a rear-end abutting portion away from the first opening is provided on the reinforcement protection cover; under the pushing action of the second connecting member, the adapter control board abuts against the rear-end abutting portion to generate a holding force perpendicular to the adapter control board.

[0018] An adapter housing provided in an embodiment of the present application comprises a protective housing having an integrally formed top cover and side guards. This embodiment also includes a bottom retaining structure detachably connected to the protective housing. Unlike the prior art, this embodiment utilizes a snap-fit assembly method, rather than a left-right snap-fit assembly. Instead, the bottom retaining structure and the top cover define a first chamber for mounting the adapter control board, while the bottom retaining structure and the side guards define a second chamber for housing the battery pack.

The battery pack adapter provided in the embodiment of the present application adopts the above-mentioned adapter housing, which is surrounded by the bottom sealing structure and the top cover to form a first chamber for installing the adapter control board. In addition, since the protective housing is an integrally formed top cover and side blocking portion, no connection gap is generated on the upper surface of the entire protective housing, which can not only effectively improve the structural strength of the battery pack adapter, but also improve the aesthetics of the product to a certain extent. The embodiment of the present application uses the locking groove and the battery pack inverted structure to engage, so that the battery pack can be stably connected to the battery pack adapter for charging, which is beneficial to improving the safety and reliability of the charging process.

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. The components of the embodiments of the present application usually described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but merely represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0029] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. In addition, the terms "first", "second", "third", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present application, it should also be noted that unless otherwise clearly defined and limited, the terms "arranged", "installed", "connected", "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0031] A USB interface and a battery pack socket are arranged on the battery pack adapter. The battery pack is fixed relative to the battery pack adapter through the battery pack socket. When the charging head is electrically connected to the USB interface, the charging head charges the battery pack through the adapter; when an external electrical device (such as a mobile phone) is electrically connected to the USB interface, the battery pack charges the external electrical device through the adapter.

[0032] Currently, the protective housing of the battery pack adapter is composed of two semi-housing structures on the left and right, and the protective housing is formed by docking and fastening the two structures on the left and right. The prior art usually uses an injection molding process to prepare the housing. Therefore, after docking and fastening, there will be gaps on the docking surfaces of the two semi-housings on the left and right, which not only affects the structural strength of the entire protective housing, but also reduces the aesthetic degree of the protective housing.

[0033] To solve the above technical problems, the embodiments of the present application provide an adapter housing and a battery pack adapter.

[0034] Referring to Figure 1 、 Figure 2 and Figure 3 As shown, the embodiments of the present application provide an adapter housing, including a protective housing 100; the protective housing 100 has an integrally formed top cover portion 101 and side blocking portions 102; it also includes a bottom blocking structure 103 detachably connected to the protective housing 100; the bottom blocking structure 103 and the top cover portion 101 enclose a first chamber 104 for installing an adapter control board 111; the bottom blocking structure 103 and the side blocking portions 102 enclose a second chamber 105 for accommodating a battery pack; one side of the side blocking portions 102 is hollowed out to form a first opening 106, and a locking groove 107 for snap-fitting with the battery pack is formed at a position of the second chamber 105 near the first opening 106, and the extending direction of the locking groove 107 is parallel to the plane where the first opening 106 is located. The battery has an inverted buckle structure corresponding to the locking groove 107 for snap-fitting.

[0035] Different from the prior art, the protective housing 100 of the embodiments of the present application is not assembled by the left-right buckling method, but the bottom blocking structure 103 and the top cover portion 101 enclose a first chamber 104 for installing an adapter control board 111; the bottom blocking structure 103 and the side blocking portions 102 enclose a second chamber 105 for accommodating a battery pack. Therefore, compared with the prior art, no connection gap can be seen on the upper surface and the side surface of the entire protective housing 100 of the embodiments of the present application, which can not only effectively improve the structural strength of the adapter housing, but also improve the aesthetics to a certain extent.

[0036] It should be noted that the bottom blocking structure 103 is installed inside the protective housing 100, and the installation and cooperation gap between the bottom blocking structure 103 and the protective housing 100 is inside the protective housing 100. Since the protective housing 100 has an integrally formed top cover portion 101 and side blocking portions 102, no connection gap of left-right buckling is generated on the entire upper surface of the entire protective housing 100.

[0037] It should be noted that the locking groove 107 in the embodiment of the present application is formed by two parts: the side blocking portion 102 near the first opening 106 and the depression on the bottom blocking structure 103. That is to say, the side blocking portion 102 near the first opening 106 is provided as one side wall of the locking groove 107. In the battery pack in cooperation with the embodiment of the present application, an inverted buckle structure is provided. When the battery pack enters the second chamber 105 through the first opening 106 formed on one side of the side blocking portion 102 and is inserted into the electrode sheet on the adapter, the inverted buckle structure can be inserted into the locking groove 107 to realize the stable assembly of the battery pack.

[0038] Specifically, as shown in Figure 3 , one side of the side blocking portion 102 in the embodiment of the present application is hollowed out to form the first opening 106. A locking groove 107 that is engaged with the battery pack is formed at a position in the second chamber 105 adjacent to the first opening 106. The extending direction of the locking groove 107 is parallel to the plane where the first opening 106 is located. The battery pack has an inverted buckle structure that is correspondingly engaged with the locking groove 107. The bottom blocking structure 103 includes a sealing cover plate 108 connected to the top cover portion 101. One side of the sealing cover plate 108 near the first opening 106 is recessed and cooperates with the side blocking portion 102 forming the first opening 106 to form the locking groove 107.

[0039] Among them, the side blocking portion 102 forming the first opening 106 simultaneously serves as one side wall of the locking groove 107. The inverted buckle structure can be abutted against the inner wall to form a blocking force perpendicular to the extending direction of the locking groove 107, improving the stability of the battery pack in the direction perpendicular to the locking groove 107.

[0040] As shown in Figure 2 , Figure 4 and Figure 5 , as an optional implementation manner, a second opening 109 is provided on one side of the top cover portion 101 away from the second chamber 105. A strengthened protection cover 110 is installed on the second opening 109. The strengthened protection cover 110 has an expanded cavity communicating with the first chamber 104 for accommodating the protruding electronic devices on the adapter control board 111.

[0041] Furthermore, in the embodiment of the present application, a second opening 109 is opened on one side of the top cover portion 101 away from the second chamber 105, and a strengthened protection cover 110 is installed on the second opening 109. In the embodiment of the present application, the strengthened protection cover 110 has an expanded cavity communicating with the first chamber 104, so that the strengthened protection cover 110 can accommodate the electronic devices with a relatively high height on the adapter control board 111, meeting the assembly space requirements of the adapter control board 111. This setting accommodates the electronic devices with a relatively high height by locally increasing the height of the adapter housing, without significantly increasing the volume of the entire adapter, making the adapter structure compact.

[0042] In addition, by providing the reinforcement protection cover 110, the structural strength of the top cover of the protection housing 100 can be enhanced in the embodiments of the present application. For example, the reinforcement protection cover 110 can be made of a material with greater strength or a structure with stronger load-bearing capacity can be provided as needed.

[0043] Referring Figure 5 As shown, as an alternative embodiment, the contact surface between the reinforcement protection cover 110 and the second opening 109 forms an inclined surface 112 that has an angle with the plane where the adapter control board 111 is located.

[0044] The inclined surface 112 has an angle with the plane where the adapter control board 111 is located. Thus, the contact surface between the reinforcement protection cover 110 and the second opening 109 is inclined. This can not only increase the contact area between the reinforcement protection cover 110 and the second opening 109, but also visually reduce the mating gap and improve the aesthetic degree. In particular, when the reinforcement protection cover 110 is mated with the protection housing 100, that is, when the inclined surface 112 is mated with the second opening 109, the protection housing 100 where the second opening 109 is located covers the inclined surface 112 of the reinforcement protection cover 110, which can maximally visually reduce the mating gap between the reinforcement protection cover 110 and the protection housing 100.

[0045] In addition, by increasing the contact area between the reinforcement protection cover 110 and the second opening 109 through the inclined surface 112, the reinforcement protection cover 110 can generate a supporting force on the top of the protection housing 100 in the vertical direction. This supporting force is formed under the action of the component force of the inclined surface 112 after the reinforcement protection cover 110 abuts against the top cover part 101. Since the inclined surface 112 surrounds the periphery of the second opening 109, it can reliably support the top cover part 101 and effectively enhance the structural strength of the top cover part 101 of the protection housing 100.

[0046] Referring Figure 5 As shown, as an alternative embodiment, the reinforcement protection cover 110 is provided with a front-end connection part 113 near the first opening 106; a first connecting piece 114 that penetrates the front-end connection part 113 and is connected to the top cover part 101 is installed on the sealing cover plate 108.

[0047] The reinforcement protection cover 110 of the embodiments of the present application is connected to the protection housing 100 through the front-end connection part 113. Specifically, the first connecting piece 114 tightly mates and connects the sealing cover plate 108, the front-end connection part 113, and the top cover part 101. That is, the first connecting piece 114 tightly mates and connects the sealing cover plate 108, the reinforcement protection cover 110, and the top cover part 101. This not only has a reliable connection, but also can reduce the number of connecting pieces and is more convenient to install.

[0048] Among them, a second connecting member 115 connected to the top cover portion 101 is installed on the adapter control board 111; there are a plurality of second connecting members 115 and they are arranged at intervals along the circumferential direction of the adapter control board 111. That is to say, the second connecting member 115 relatively fixes the adapter control board 111 and the top cover portion 101, thereby realizing the fixation of the adapter control board 111.

[0049] It should be noted that the first connecting member 114 and the second connecting member 115 can adopt bolt connecting members or other types of connecting members, and those skilled in the art can choose according to needs.

[0050] Refer to Figure 5 、 Figure 6 As shown, as an optional implementation manner, a rear end abutting portion 116 away from the first opening 106 is provided on the strengthening protection cover 110, and the adapter control board 111 abuts against the rear end abutting portion 116 under the pushing action of the second connecting member 115, generating a holding force perpendicular to the adapter control board 111. Specifically, the rear end abutting portion 116 has an end face close to the adapter control board 111, and this end face abuts against the board surface of the adapter control board 111, thereby generating a holding force perpendicular to the board surface of the adapter control board 111.

[0051] That is to say, in the embodiment of the present application, under the action of the second connecting member 115, the adapter control board 111 is pressed by the rear end abutting portion 116 to generate a thrust perpendicular to the adapter control board 111. Therefore, the rear end abutting portion 116 and the second connecting member 115 cooperate to realize the vertical limit and fixation of the adapter control board 111.

[0052] As described above, a second connecting member 115 connected to the top cover portion 101 is installed on the adapter control board 111. Specifically, the second connecting member 115 is a bolt connecting member. To facilitate the installation of the second connecting member 115, the top cover portion 101 is provided with a fitting member that cooperates with the second connecting member 115. Specifically, the fitting member is a hollow stud, and the hollow stud extends vertically, and the bolt connecting member cooperates with the hollow stud to achieve fixation. In this embodiment, the rear end abutting portion 116 is in the shape of a hollow cylinder, and the fitting member fits with the hollow wall surface of the rear end abutting portion 116, which not only plays a role in limiting, but also can make the structure of the adapter more compact, and the design is very ingenious. Preferably, the rear end abutting portion 116 is partially cut along the vertical direction, which not only plays a role in limiting, but also is more convenient to install due to being partially cut.

[0053] Among them, the front end connecting portion 113 also has a blocking platform 118 that contacts the side surface of the adapter control board 111, and is used to generate a blocking force whose extending direction is perpendicular to the holding force. Thus, the adapter control board 111 is limited in two perpendicular directions, and the installation of the adapter control board 111 is more stable and reliable.

[0054] In summary, the embodiment of the present application not only generates a supporting force perpendicular to the adapter control board 111 through the rear abutment portion 116 and the front connection portion 113, but also provides a blocking force horizontally against the adapter control board 111 through the blocking platform 118 provided on the front connection portion 113. In other words, while the embodiment of the present application strengthens the fixation of the protective cover 110 through the first and second connectors 114 and 115, it also limits the position of the adapter control board 111 in both directions and secures the adapter control board 111.

[0055] Furthermore, a front abutment platform 117 is provided on the front connecting portion 113 ; the front abutment platform 117 and the blocking platform 118 form a stepped surface, which can be engaged with the adapter control board 111 , making it easier to position the adapter control board 111 during installation.

[0056] Reference Figure 2 and Figure 5 As shown, as an optional embodiment, bottom sealing structure 103 further includes an electrode seat cover plate 119. Electrode seat cover plate 119 is located farther from first opening 106 than sealing cover plate 108. Electrode seat cover plate 119 and sealing cover plate 108 are arranged sequentially in a direction perpendicular to the extension direction of locking groove 107 and have a coplanar portion. In other words, electrode seat cover plate 119 and sealing cover plate 108 form a relatively large bottom surface that can abut against the battery pack, thereby facilitating positioning of the battery pack during installation.

[0057] In the embodiment of the present application, an electrode sheet that is plugged into and fits with the battery pack is provided on the electrode seat cover 119 for electrically connecting to the battery pack, thereby charging the battery pack or utilizing the battery pack to discharge the battery pack.

[0058] An embodiment of the present application provides a battery pack adapter, comprising the above-mentioned adapter housing and an adapter control board 111 disposed in the first chamber 104 of the adapter housing.

[0059] The battery pack adapter provided in the embodiment of the present application utilizes the aforementioned adapter housing, which, through the bottom blocking structure 103 and the top cover portion 101, forms a first chamber 104 for mounting the adapter control board 111. Furthermore, because the protective housing 100 is formed integrally with the top cover portion 101 and the side retaining portion 102, there are no connection gaps on the entire upper surface of the protective housing 100. This not only effectively enhances the structural strength of the battery pack adapter, but also improves the product's aesthetics to a certain extent. The embodiment of the present application utilizes the locking slot 107 to engage the battery pack's inverted structure, allowing the battery pack to stably connect to the battery pack adapter for charging, thereby improving the safety and reliability of the charging process.

[0060] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various modifications and variations can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
