[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0035] 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 present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0036] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. In addition, the terms "first," "second," "third," etc. are used only to distinguish the descriptions and are not to be understood as indicating or implying relative importance.

[0037] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0038] The battery pack adapter is equipped with a USB port and a battery pack socket. The battery pack is fixed to the battery pack adapter via the battery pack socket. When the charging head is electrically connected to the USB port, the charging head charges the battery pack through the adapter. When an external power device (such as a mobile phone) is electrically connected to the USB port, the battery pack charges the external power device through the adapter.

[0039] The protective housing of a current battery pack adapter consists of two parts, left and right, that are joined together to form the protective housing. Existing technology typically uses injection molding to produce the housing. This creates a gap between the two parts after they are joined together, creating a discordant gap on the top surface of the protective housing that is easily visible to the user, affecting its aesthetics.

[0040] Reference Figure 1 、 Figure 2 as well as Figure 3 As shown, an embodiment of the present application provides an adapter housing, comprising a protective housing 100 having an integrally formed top cover 101 and side guards 102; and further comprising a bottom retaining structure 103 detachably connected to the protective housing 100. The bottom retaining structure 103 and the top cover 101 enclose a first chamber 104 for mounting an adapter control board 111. The bottom retaining structure 103 and the side guards 102 enclose a second chamber 105 for accommodating a battery pack.

[0041] The integral molding may be integral injection molding, or may be 3D printing or machining molding. Since injection molding has a lower production cost in mass production, the protective housing 100 is usually formed by injection molding.

[0042] Unlike the prior art, the protective housing 100 of this embodiment is assembled without snapping together. Instead, the bottom sealing structure 103 and the top cover 101 define a first chamber 104 for mounting the adapter control board 111. The bottom sealing structure 103 and the side retaining members 102 define a second chamber 105 for housing the battery pack. This eliminates visible gaps on the top and side surfaces of the protective housing 100, which are easily visible to the user. This significantly enhances the aesthetics of the housing.

[0043] It should be noted that the bottom sealing structure 103 is installed inside the protective shell 100, and the installation fitting clearance between the bottom sealing structure 103 and the protective shell 100 is inside the protective shell 100. Users cannot see these gaps during use, and this safety fitting clearance will not affect the aesthetics of the adapter shell.

[0044] Although the protective shell 100 and the bottom sealing structure 103 formed by the upper and lower arrangements can eliminate gaps, due to the limitations of the injection molding and demolding direction, the shell cannot be directly injection molded to form a mounting structure that can reliably fix the electrode holder 113, which is not conducive to reliable connection with the battery pack.

[0045] To solve the above technical problems, an embodiment of the present application provides an adapter housing and a battery pack adapter.

[0046] Reference Figure 1 、 Figure 2 as well as Figure 3 As shown, an embodiment of the present application provides an adapter shell, including a protective shell 100; the protective shell 100 has a top cover portion 101 and a side stop portion 102, and the top cover portion 101 and the side stop portion 102 are integrally formed; it also includes a bottom sealing structure 103 detachably connected to the protective shell 100; the bottom sealing structure 103 and the top cover portion 101 form a first chamber 104 for installing an adapter control board 111; the bottom sealing structure 103 includes an electrode seat 113 for plugging into a battery pack, and the electrode seat 113 is provided with a mounting member 112 detachably connected to the protective shell 100 on the side away from the battery pack, and a card slot 117 with an opening facing the electrode seat 113 is provided on the mounting member 112, and the portion of the electrode seat 113 facing away from the battery pack is connected to the card slot 117.

[0047] In the embodiment of the present application, the electrode holder 113 is snap-assembled by a mounting member 112 detachably connected to the protective shell 100. The mounting member 112 can limit the electrode holder 113 in multiple directions, thereby achieving reliable installation of the electrode holder 113, which is beneficial to the precise alignment of the battery pack and the electrode holder 113 for plugging.

[0048] It should be noted that the battery pack is provided with a conductive structure that contacts and electrically connects to the electrode holder 113. The specific structure of the conductive structure and the electrode holder 113 can be selected by those skilled in the art as needed. No special limitation is imposed here.

[0049] Exemplarily, the battery pack has a slot, the conductive structure is a U-shaped metal clip, and the electrode holder 113 includes a metal sheet 125 that can be inserted into the U-shaped metal clip. The U-shaped metal clip clamps the metal sheet 125 so that the inner wall surfaces of the U-shaped metal clip are aligned with the metal sheet 125. This not only provides a larger contact surface between the metal sheet 125 and the U-shaped metal clip, but also ensures a moderately tight fit with the metal sheet 125, increasing the stability of the connection between the battery pack and the battery pack adapter.

[0050] Reference Figure 2As shown, as previously described, in the embodiment of the present application, the chamber formed in the protective housing 100 is divided into a first chamber 104 and a second chamber 105 by a bottom sealing structure 103. The bottom sealing structure 103 can be arranged horizontally, with the first chamber 104 formed on the upper side of the bottom sealing structure 103 and the second chamber 105 formed on the lower side of the bottom sealing structure 103. This achieves a compact arrangement of the battery pack and the adapter control board 111 in the vertical direction, which helps to reduce the volume of the adapter housing and avoid occupying a large space.

[0051] Specifically, the bottom blocking structure 103 and the side blocking portion 102 form a second chamber 105 for accommodating the battery pack; one side of the side blocking portion 102 is hollowed out to form a first opening 106 , and the battery pack enters the second chamber 105 through the first opening 106 .

[0052] It should be noted that the bottom blocking structure 103 of the embodiment of the present application includes an electrode seat 113 for connecting with the battery pack. The electrode seat 113 is located in the side blocking portion 102. After the battery pack enters the second chamber 105 through the first opening 106, it is electrically connected to the electrode seat 113.

[0053] Reference Figure 3 As shown, a mounting member 112 is provided on the side of the electrode holder 113 away from the battery pack, which is detachably connected to the protective housing 100. In this embodiment of the application, a slot 117 is provided on the mounting member 112 with an opening toward the electrode holder 113, so that the portion of the electrode holder 113 away from the battery pack can be connected to the slot 117.

[0054] Reference Figure 4 As shown, it should be noted that the mounting member 112 of the embodiment of the present application is a U-shaped structural member as a whole; the slot 117 includes a first slot 118 located at the bottom of the U-shaped structural member and a second slot 119 located on both sides of the U-shaped structural member. After the electrode holder 113 is plugged into the first slot 118 on the U-shaped structural member, the first slot 118 can generate a blocking force extending along the direction of plug-in movement, and can clamp the electrode holder 113 in the up and down directions to prevent its displacement in the up and down directions. The second slot 119 of the embodiment of the present application is on both sides of the electrode holder 113, which can not only limit the left and right displacement of the electrode holder 113, but also limit the up and down displacement of the electrode holder 113. The stable positioning of the electrode holder 113 is achieved as a whole.

[0055] Compared with the prior art, the embodiment of the present application uses a mounting member 112 that is detachably connected to the protective shell 100 to snap-fit the electrode holder 113. The mounting member 112 can limit the electrode holder 113 in multiple directions, thereby achieving reliable installation of the electrode holder 113, which is beneficial to the precise alignment of the battery pack and the electrode holder 113 for plugging.

[0056] Reference Figure 3As shown, as an alternative embodiment, a slidable guiding structure 107 is detachably connected to the inner wall of the side blocking portion 102. The slidable guiding structure 107 is located on opposite sides of the first opening 106, and the guiding path of the slidable guiding structure 107 is perpendicular to the plane where the first opening 106 is located; the battery pack is driven to slide along the slidable guiding structure 107 and enter the second chamber 105.

[0057] Furthermore, in the embodiment of the present application, the slidable guiding structure 107 is arranged on opposite sides of the first opening 106, and a sliding groove cooperating with the slidable guiding structure 107 is provided on the battery pack. The user can hold the battery pack and cooperate the sliding groove on the battery pack with the slidable guiding structure 107, and then push the battery pack. Through the guiding of the slidable guiding structure 107, the battery pack enters the second chamber 105 and is connected to the electrode seat 113.

[0058] It should be noted that the bottom of the second chamber 105 is a hollow structure to facilitate the installation of the battery pack. The slidable guiding structure 107 is a strip-shaped structural member, and the battery pack can only move along its guiding path on the slidable guiding structure 107. Therefore, the slidable guiding structure 107 can achieve precise guiding of the battery pack to ensure that the battery pack and the electrode seat 113 can be accurately plugged in.

[0059] Refer to Figure 3 As shown, as an alternative embodiment, the slidable guiding structure 107 is provided with a plugging portion 120 whose extending direction is parallel to the guiding path; a socket 121 cooperating with the plugging portion 120 is formed on the mounting member 112, and a connection hole 126 perpendicular to the guiding path is formed on the mounting member 112. A connection structure passing through the plugging portion 120 and connecting to the protection housing 100 is provided in the connection hole.

[0060] Furthermore, in the embodiment of the present application, the slidable guiding structure 107 is provided with a plugging portion 120, and a socket 121 cooperating with the plugging portion 120 is formed on the mounting member 112, so that the slidable guiding structure 107 can be horizontally inserted into the mounting member 112 through the plugging portion 120 to realize the connection of the slidable guiding structure 107 with the mounting member 112 and the protection housing 100.

[0061] Refer to Figure 3 As shown, as an alternative embodiment, the socket 121 is a part of the card slot 117, and the socket 121 is located on opposite sides of the card slot 117.

[0062] Specifically, refer to Figure 4 As shown, as described above, the mounting member 112 is a U-shaped structural member as a whole; the card slot 117 on the mounting member 112 includes a first card slot 118 located at the bottom of the U-shaped structural member and a second card slot 119 located on both sides of the U-shaped structural member. In this embodiment, the socket 121 is a part of the second card slot 119 and is arranged at both sides of the U-shaped mounting member 112.

[0063] It should be noted that the insertion part 120 can be inserted into the socket 121 along the guiding path. Similarly, the electrode base 113 is inserted into the first clamping groove 118 and the second clamping groove 119 along the guiding path. That is to say, the clamping groove 117 provided on the mounting member 112 can be clamped with the electrode base 113 and the sliding guiding structure 107 at the same time. After the above clamping is completed, the sliding guiding structure 107 is arranged on both sides of the electrode base 113, and the structure is reasonable and compact.

[0064] Refer to Figure 6 、 Figure 8 As shown, a connecting column 127 with an extending direction perpendicular to the guiding path is arranged in the protection housing 100; there are two connecting holes 126, which respectively penetrate through the two side walls of the mounting member 112 (i.e., the upper and lower side walls of the clamping groove 117). The connecting column 127 passes through the connecting hole 126 near the top cover part 101 and abuts against the insertion part 120. The connecting structure is inserted from the connecting hole 126 far from the top cover part 101 and penetrates through the insertion part 120 to be connected with the connecting column 127. The synchronous locking of the mounting member 112, the sliding guiding structure 107 and the protection housing 100 is realized.

[0065] In this embodiment, the connecting structure is a screw (not shown). Circular holes aligned with the connecting hole 126 far from the top cover part 101 are respectively provided on the insertion part 120 and the connecting column 127, and threads are provided in the circular holes on the connecting column 127. The screw sequentially passes through the connecting hole 126 far from the top cover part 101, the circular hole on the insertion part 120 and is fixed to the threaded circular hole on the connecting column 127, realizing the synchronous locking of the mounting member 112, the sliding guiding structure 107 and the protection housing 100. The embodiment of the present application can effectively reduce the number of installations of connecting parts such as screws on the adapter housing, has a compact structure, and can reduce the manufacturing cost to a certain extent.

[0066] In this embodiment, the connecting column 127 is a tapered column, and the diameter of the connecting column 127 gradually increases along the direction close to the top cover part 101. Thus, during the process of the mounting member 112 being inserted into the protection housing 100, when the connecting hole 126 of the mounting member 112 near the top cover part 101 is sleeved on the connecting column 127, and the connecting column 127 with a gradually increasing diameter is tightly fitted with the connecting hole 126 near the top cover part 101, the mounting member 112 is inserted in place. Therefore, the tapered connecting column 127 can limit the installation of the mounting member 112.

[0067] Furthermore, refer to Figure 8 、 Figure 9 and Figure 10As shown, protrusions 128 are provided on opposite sides of the electrode holder 113. The protrusions 128 are sandwiched between the plug portion 120 and the inner wall surface of the mounting member 112. These protrusions 128 limit the position of the electrode holder 113 in a direction perpendicular to the guide path. Preferably, the surface of the connecting post 127 forms a cutting plane, and the protrusions 128 abut against the cutting plane, thereby limiting the position of the electrode holder 113 in the direction of the guide path.

[0068] It should be noted that a sliding groove may be provided on the sliding guide structure 107 and a matching guide portion may be provided on the side block portion 102 , so that the sliding guide structure 107 and the side block portion 102 can simultaneously achieve a sliding matching connection.

[0069] For example, refer to Figure 5 、 Figure 6 As shown, the sliding guide structure 107 is provided with a first sliding groove 109 with an L-shaped cross-section, and the extension direction of the first sliding groove 109 is consistent with the guide path of the sliding guide structure 107; the side blocking portion 102 is provided with a first guide portion 110 that is connected to the first sliding groove 109; the first guide portion 110 forms a flange structure, and the flange structure abuts against the first sliding groove 109 to generate a supporting force perpendicular to the extension direction of the first sliding groove 109 (the same as the guide path of the sliding guide structure 107).

[0070] The first sliding groove 109 and the first guide portion 110 can generate two limiting forces with perpendicular action directions, so that the sliding guide structure 107 is stably connected to the side block portion 102, and can effectively prevent the sliding guide structure 107 from shaking on the side block portion 102.

[0071] Further, refer to Figure 6 As shown, a second slide groove 114 is formed at the connection between the side blocking portion 102 and the bottom blocking structure 103, and the extension direction of the first slide groove 109 is consistent with the guide path of the sliding guide structure 107; the sliding guide structure 107 has a second guide portion 115, and the second guide portion 115 is cooperatively connected with the second slide groove 114.

[0072] Reference Figure 6 As shown, as an optional embodiment, the electrode seat 113 has an electrode seat cover 116; the bottom sealing structure 103 also includes a sealing cover 108 connected to the top cover 101, and the electrode seat cover 116 and the sealing cover 108 are arranged sequentially along the guide path and have a coplanar portion, and the electrode seat cover 116 is away from the first opening 106.

[0073] It should be noted that the electrode seat 113 of the embodiment of the present application has an electrode seat cover 116 , and the electrode seat cover 116 and the sealing cover 108 isolate the internal space of the protective shell 100 to form a first chamber 104 and a second chamber 105 .

[0074] Wherein, a clamping structure is provided on one side of the sealing cover plate 108, and the side surface of the electrode seat cover plate 116 close to the first opening 106 is connected to the clamping structure.

[0075] Exemplarily, a stepped structure is provided on the side of the sealing cover plate 108 close to the electrode seat cover plate 116, and the sealing cover plate 108 abuts against the electrode seat cover plate 116 through the stepped structure.

[0076] It should be noted that the electrode seat cover plate 116 and the sealing cover plate 108 abut against each other to prevent a large assembly gap from being generated. Those skilled in the art can set other types of clamping structures as needed, and the purpose is to realize the fitting connection between the sealing cover plate 108 and the electrode seat cover plate 116.

[0077] Referring to Figure 1 、 Figure 7 As shown, as an alternative embodiment, a second opening 122 is provided at the position of the top cover portion 101 corresponding to the adapter control board 111. A strengthening protection cover 123 is provided in the second opening 122. The strengthening protection cover 123 has an expanded cavity communicating with the first chamber 104, and the expanded cavity is used to accommodate the protruding electronic devices on the adapter control board 111.

[0078] Wherein, a connecting portion is provided on the strengthening protection cover 123; the connecting portion is fixedly clamped between the top cover portion 101 and the sealing cover plate 108.

[0079] It should be noted that the plane where the second opening 122 is located, the plane where the adapter control board 111 is located, and the covering plane of the bottom blocking structure 103 are parallel and spaced in sequence.

[0080] Furthermore, in the embodiment of the present application, a second opening 122 is opened on the side of the top cover portion 101 away from the second chamber 105, and a strengthening protection cover 123 is installed on the second opening 122. The expanded cavity of the strengthening protection cover 123 in the embodiment of the present application 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 can meet the requirement of local height increase of the entire protection housing 100, and will not significantly increase the volume of the entire adapter.

[0081] In addition, through the setting of the strengthening protection cover 123 in the embodiment of the present application, the structural strength of the top cover portion 101 of the protection housing 100 can also be enhanced. For example, the strengthening protection cover 123 can be made of a material with a relatively high strength or a structure with a relatively strong load-bearing capacity can be set as needed.

[0082] Referring to Figure 1 、 Figure 2 And Figure 7As shown, as an alternative embodiment, the contact surface between the enhanced protection cover 123 and the second opening 122 forms an inclined surface 124 that has an angle with the plane where the adapter control board 111 is located.
