[0002] This application claims priority to Chinese patent application No. 202421476752.0, entitled "Battery Pack Adapter", filed on June 26, 2024, with China Patent Office. Technical Field
[0003] This application relates to the field of charging equipment technology, and more specifically, to an adapter housing and a battery pack adapter. Background Technology
[0004] The battery pack adapter features a USB port and a battery pack connector for charging the battery packs of portable power tools. Currently, the protective housing of the battery pack adapter consists of two parts, left and right, which are joined together to form the protective housing. To accommodate the battery pack, existing technology uses sliding guide grooves on both the left and right housing parts to guide the battery pack and ensure it contacts the electrode plates on the electrode holder for charging. However, because the housing structure is injection molded, the injection molding direction limits the internal wall to a single type of groove. Over long-term use, repeated insertion and removal of the battery pack from the groove causes structural wear, increasing the clearance and ultimately reducing the accuracy of the sliding guide. Furthermore, this makes the battery pack prone to loosening after insertion, failing to reliably secure it during charging. Utility Model Content

[0028] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings for the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only some 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 accompanying drawings can be arranged and designed in various different configurations.
[0029] 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 only 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 making creative efforts are within the scope of protection of the present application.
[0030] 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 and explained in the subsequent drawings. In addition, the terms "first", "second", "third" and the like are only used to distinguish description, and cannot be understood as indicating or implying relative importance.
[0031] In the description of the present application, it should also be noted that, unless otherwise explicitly specified and limited, the terms "setting", "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or detachably connected, or integrally connected; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0032] The USB interface and the battery pack socket are arranged on the battery pack adapter, and the battery pack is fixed relative to the battery pack adapter through the battery pack socket. When the charging head is electrically connected with the USB interface, the charging head charges the battery pack through the adapter; when the external power consumption equipment (such as a mobile phone) is electrically connected with the USB interface, the battery pack charges the external power consumption equipment through the adapter.
[0033] The protection shell of the battery pack adapter is currently composed of left and right shell structures, and the protection shell is formed by butt joint and buckling of the left and right shell structures. The existing technology usually adopts an injection molding process to prepare the shell, so that after butt joint and buckling, a gap will be generated on the butt joint surface of the left and right shell halves, which not only affects the structural strength of the entire protection shell, but also reduces the aesthetic level of the protection shell.
[0034] Referring to Figure 1 , Figure 2 and Figure 3 , the embodiment of the present application provides an adapter shell, which comprises a protection shell 100; the protection shell 100 has an integrally formed top cover part 101 and a side blocking part 102; further comprising a bottom blocking structure 103 detachably connected with the protection shell 100; the bottom blocking structure 103 and the top cover part 101 enclose a first cavity 104 for mounting an adapter control panel 111; the bottom blocking structure 103 and the side blocking part 102 enclose a second cavity 105 for accommodating a battery pack.
[0035] As can be seen, unlike the prior art, the protection shell 100 of the embodiment of the present application is not assembled in a left-right buckling manner, but a first cavity 104 for mounting an adapter control panel 111 is enclosed by the bottom blocking structure 103 and the top cover part 101; a second cavity 105 for accommodating a battery pack is enclosed by the bottom blocking structure 103 and the side blocking part 102. The upper surface and the side surface of the protection shell 100 will not see a connection gap, which not only effectively improves the structural strength of the adapter shell, but also improves the aesthetic appearance to some extent.
[0036] It should be noted that the bottom blocking structure 103 is installed inside the protection shell 100, and the installation fit clearance between the bottom blocking structure 103 and the protection shell 100 is inside the protection shell 100. Since the protection shell 100 is an integrally formed top cover part 101 and side blocking part 102, the entire upper surface of the entire protection shell 100 does not produce a left-right buckling connection gap.
[0037] In order to realize the installation of the battery pack, the prior art sets a sliding guide groove capable of cooperating with the battery pack on each of the left and right shell halves to guide the battery pack while enabling the battery pack to contact the electrode sheet of the electrode seat to realize charging. Since the shell structure is an injection molded structure, the structure of the sliding groove on the inner wall of the shell can only be a single structure due to the limitation of the injection demolding direction. In the long-term use of the battery pack adapter, repeated plugging and unplugging of the battery pack and the sliding groove will cause structural wear, resulting in an increase in the fit clearance and ultimately reducing the accuracy of the sliding guide. In addition, the battery pack is also prone to loosening after being plugged into the adapter, and cannot be reliably fixed during charging.
[0038] To solve the above technical problems, the embodiment of the present application provides an adapter shell and a battery pack adapter.
[0039] Referring to Figure 1 , Figure 2 and Figure 3 , the embodiment of the present application provides an adapter shell, which comprises a protective shell 100; the protective shell 100 has an integrally formed top cover part 101 and a side blocking part 102; further comprising a bottom blocking structure 103 connected with the protective shell 100; the bottom blocking structure 103 and the top cover part 101 form a first cavity 104 for installing an adapter control panel 111; the bottom blocking structure 103 and the side blocking part 102 form a second cavity 105 for accommodating a battery pack; one side of the side blocking part 102 is hollowed out to form a first opening 106, and the side blocking part 102 on both sides of the first opening 106 is provided with a detachable guide structure 107 for guiding the battery pack from the first opening 106 to a preset position in the second cavity 105.
[0040] One side of the side blocking part 102 of the embodiment of the present application is hollowed out to form a first opening 106, and the side blocking part 102 on both sides of the first opening 106 is provided with a detachable guide structure 107 for guiding the battery pack from the first opening 106 to a preset position in the second cavity 105.
[0041] Unlike the prior art, the detachable connection of the guide structure 107 and the protective shell 100 makes the protective shell 100 and the guide structure 107 two independent structures, which meets the requirement of integrally forming the protective shell 100, and enables the detachable installation of the guide structure 107, so that the independent guide structure 107 can be quickly replaced after the battery pack and the guide structure 107 are worn out, eliminating the assembly gap between the battery pack and the guide structure 107, and realizing the precise guidance and fixation of the battery pack.
[0042] The embodiment of the present application can ensure the precise insertion of the battery pack and the electrode sheet 120 through the precise guidance of the battery pack.
[0043] It should be noted that the detachable connection mode of the guide structure 107 and the protective shell 100 of the embodiment of the present application is not limited, and those skilled in the art can set it according to the needs.
[0044] For example, the guide structure 107 and the protective shell 100 are fixedly connected by bolts, specifically, one end of the guide structure 107 away from the first opening 106 is detachably connected with the protective shell 100 by a bolt. Alternatively, the guide structure 107 and the protective shell 100 are connected by a clamping structure.
[0045] Referring to Figure 4 , Figure 5As shown, the guiding structure 107 is provided with a first sliding groove 109 in L-shaped cross section, and the first sliding groove 109 extends in the same direction as the guiding path of the guiding structure 107. The side blocking part 102 is provided with a first guiding part 110 connected with the first sliding groove 109. The first guiding part 110 forms a flange structure, and the flange structure abuts against the first sliding groove 109 to generate a resisting force perpendicular to the extension direction of the first sliding groove 109.
[0046] It should be noted that the first sliding groove 109 is arranged on the guiding structure 107, and the first guiding part 110 is arranged on the side blocking part 102, so as to realize the sliding clamping of the guiding structure 107 and the side blocking part 102.
[0047] In the embodiment, the first sliding groove 109 is in L shape, and the first guiding part 110 forms a flange structure capable of cooperating with the L-shaped first sliding groove 109. When the guiding structure 107 is inserted into the protective shell 100 along the extension direction of the first sliding groove 109 (i.e. the guiding path direction of the guiding structure 107), the first guiding part 110 and the first sliding groove 109 are in sliding clamping cooperation.
[0048] It should be noted that the first sliding groove 109 and the first guiding part 110 can generate limiting forces in two directions, and the directions of the two limiting forces are perpendicular. Specifically, the first sliding groove 109 and the first guiding part 110 cooperate to generate limiting forces in two directions (left-right direction and up-down direction) perpendicular to the guiding path direction (front-rear direction) of the guiding structure 107, which does not affect the insertion of the guiding structure 107 into the protective shell 100, and can limit the guiding structure 107 in the other two directions. The stable connection of the guiding structure 107 and the side blocking part 102 can effectively prevent the guiding structure 107 from shaking on the side blocking part 102.
[0049] Referring to Figure 4 As an optional embodiment, the guiding structure 107 includes a flat plate part 112 and a raised part 113. On the side away from the side blocking part 102, the thickness of the raised part 113 is greater than that of the flat plate part 112, and the first sliding groove 109 is formed on the raised part 113.
[0050] Further, the guiding structure 107 includes the flat plate part 112 and the raised part 113. The flat plate part 112 is in large-area adhesion with the side blocking part 102 of the protective shell 100, so that the installation of the guiding structure 107 is more stable. The raised part 113 cooperates with the guiding groove arranged on the battery pack to realize the sliding guiding connection of the adapter and the battery pack. The first sliding groove 109 is formed on the relatively thick raised part 113, which makes full use of the space of the raised part 113 and is beneficial to the miniaturization of the adapter structure.
[0051] It should be noted that the protruding part 113 of the embodiment of the present application is a strip-shaped structure, and the extension path thereof is the guiding path of the battery pack. The protruding part 113 on both sides of the first opening 106 can form a clamping effect on the left and right of the battery pack, which is beneficial to enhance the stability of the battery pack during charging.
[0052] Referring to Figure 5 Further, the second chute 114 is formed at the connection between the side blocking part 102 and the bottom blocking structure 103, and the extension direction of the second chute 114 is consistent with the guiding path direction of the guiding structure 107. The guiding structure 107 has a second guiding part 115, and the second guiding part 115 is connected with the second chute 114 in a matched manner.
[0053] In the embodiment, the second guiding part 115 is formed on the side of the flat plate part 112 away from the protruding part 113. As described above, the setting of the flat plate part 112 can increase the contact surface between the guiding structure 107 and the side blocking part 102. In combination with the first guiding part 110 and the second guiding part 115 arranged at intervals, the operation of sliding the guiding structure 107 into the protective shell 100 is more stable, and the limiting force generated at the positions of the first guiding part 110 and the second guiding part 115 can effectively enhance the stability between the guiding structure 107 and the side blocking part 102.
[0054] Referring to Figure 3 , Figure 5 As an optional embodiment, the bottom blocking structure 103 includes a sealing cover plate 108 connected with the top cover part 101, and the covering plane of the sealing cover plate 108 is parallel to the guiding path of the guiding structure 107.
[0055] In the embodiment, the sealing cover plate 108 is detachably connected with the top cover part 101 by screws. The covering plane of the sealing cover plate 108 refers to the surface of the sealing cover plate 108 away from the first chamber 104. The covering plane abuts against the battery pack, so that the battery pack is limited at the covering plane.
[0056] Further, the bottom blocking structure 103 further includes an electrode seat cover plate 116, the electrode seat cover plate 116 is arranged along the guiding path with the sealing cover plate 108, and the electrode seat cover plate 116 is away from the first opening 106. The electrode seat cover plate 116 is provided with an electrode sheet 120 which can be plugged with the battery pack, and the electrode sheet 120 extends along the guiding path.
[0057] In the embodiment of the present application, the electrode seat cover plate 116 provided with the electrode sheet 120 cooperates with the sealing cover plate 108 to divide the protective shell 100 into the first chamber 104 and the second chamber 105 arranged in an upper-lower manner. The electrode seat cover plate 116 is reasonably utilized, the structure design is reasonable, and the adapter shell structure is compact.
[0058] Preferably, the side surface portion of the electrode seat cover plate 116 away from the first chamber 104 is coplanar with the covering plane of the sealing cover plate 108 to increase the area for mating with the battery pack and improve the stability of the battery pack installation.
[0059] Referring to Figure 6 As an optional embodiment, the sealing cover plate 108 is provided with a step structure 117 on one side, and the portion of the electrode seat cover plate 116 close to the first opening 106 abuts against the step structure 117.
[0060] The sealing cover plate 108 of the embodiment of the application is spliced with the electrode seat cover plate 116 through the step structure 117, and the mutual abutment of the sealing cover plate 108 and the electrode seat cover plate 116 realizes reliable connection.
[0061] Referring to Figure 3 , Figure 4 Further, the guide structure 107 is provided with a first limiting portion 118 on one side of the bottom blocking structure 103; one part of the first limiting portion 118 abuts against the sealing cover plate 108, and the other part abuts against the electrode seat cover plate 116. Thus, the first limiting portion 118 simultaneously limits the sealing cover plate 108 and the electrode seat cover plate 116 in the direction towards the first chamber 104.
[0062] Referring to Figure 7 The top cover portion 101 is provided with a second limiting portion 119 on the other side of the bottom blocking structure 103; one part of the second limiting portion 119 abuts against the sealing cover plate 108, and the other part abuts against the electrode seat cover plate 116. Thus, the second limiting portion 119 simultaneously limits the sealing cover plate 108 and the electrode seat cover plate 116 in the direction towards the second chamber 105.
[0063] In summary, the first limiting portion 118 of the embodiment of the application can generate a force perpendicular to the sealing cover plate 108 and the electrode seat cover plate 116 to realize the upward force in the vertical direction on the sealing cover plate 108 and the electrode seat cover plate 116. The second limiting portion 119 of the embodiment of the application can generate a downward force in the vertical direction by one part abutting against the sealing cover plate 108 and the other part abutting against the electrode seat cover plate 116. The first limiting portion 118 and the second limiting portion 119 realize the upward and downward clamping and fixing of the sealing cover plate 108 and the electrode seat cover plate 116.
[0064] The embodiment of the application provides a battery pack adapter, which comprises the adapter shell and the adapter control board 111 arranged in the first chamber 104 of the adapter shell.
[0065] The battery pack adapter provided by the embodiment of the present application adopts the adapter shell described above, which can realize replacement of the guide structure 107 after long-term wear by being detachably replaced, thereby eliminating the guide assembly gap between the battery pack and the guide structure 107. The battery pack adapter of the embodiment of the present application can ensure that the battery pack provides accurate guidance when the battery pack is plugged in for charging. In addition, the problem of the battery pack not being fixed firmly due to the gap can also be avoided.
[0066] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Various modifications and changes can be made by those skilled in the art based on the spirit and principles of the present application.
