[0040] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0041] like Figure 1 As shown, a pull rod type power supply housing (hereinafter referred to as power supply housing) of an embodiment of the utility model includes a housing 1, a pull rod 2 and a fixing assembly 3.

[0042] The housing 1 is used to install a battery module, for example Figure 1 As shown, the shell 1 can be generally in the shape of a square box, and the shell 1 as a whole is a sealed structure. The battery module can include a plurality of single cells, and the battery module can be installed and fixed in the shell 1.

[0043] like Figure 1 As shown, the pull rod 2 includes a pull rod body 21 and a gripping portion 22 fixed to one end of the pull rod body 21. The pull rod body 21 may be a rod-shaped structure and may extend in the up-down direction, and the gripping portion 22 may be provided at the top of the pull rod body 21, and the gripping portion 22 may be a handle or the like, so that the power supply housing is conveniently held by a person when moving.

[0044] The fixing assembly 3 detachably mounts the pull rod body 21 on the side wall of the housing 1. For example, Figure 1 As shown, the fixing assembly 3 may include structural members such as fasteners, fixing members, and fixing plates, and a portion of the pull rod body 21 may be directly connected and fixed to the rear side wall of the housing 1 through the fixing assembly 3 .

[0045] The pull rod 2 of the power housing of this embodiment is detachably assembled on the housing 1 through the fixing assembly 3, and the pull rod 2 can be removed during transportation, thereby avoiding the situation where the pull rod 2 protrudes from the top side of the housing 1 and is not easy to pack and transport.

[0046] In some embodiments, the fixing assembly 3 includes a pressing plate 31, which is pressed on the peripheral side of the pull rod body 21 and is detachably fixed to the housing 1. Figure 2 As shown, the pressure plate 31 can be generally a U-shaped structure, and the pressure plate 31 can be pressed on a portion of the circumference of the pull rod body 21, and the left and right ends of the pressure plate 31 can be connected and fixed to the shell 1 by fasteners, thereby ensuring the fixing effect of the pull rod body 21.

[0047] In some embodiments, the rod body 21 is retractable and has an extended state and a retracted state. In the extended state, the rod body 21 extends upward, and in the retracted state, the top of the rod body 21 is close to the top surface of the housing 1.

[0048] For example, Figure 3 As shown, the pull rod body 21 is in an extended state, at which time the pull rod body 21 extends upward and can raise the height of the gripping portion 22, thereby facilitating the gripping of a person's hand. When it is not necessary to move, the pull rod body 21 can be pressed downward, at which time the overall height of the pull rod body 21 will be reduced, thereby reducing the height of the gripping portion 22, making it easier to store and organize.

[0049] In some embodiments, the pull rod body 21 includes an outer rod 213 and an inner rod 214 , the inner rod 214 is slidably assembled in the outer rod 213 to achieve the retractability of the pull rod 2 , and the pressure plate 31 is pressed on the peripheral side of the outer rod 213 and is connected and fixed to the shell 1 .

[0050] For example, Figure 3 As shown, the outer rod 213 can be roughly square tube-shaped, and the outer rod 213 can be directly covered on the outer peripheral side of the outer rod 213 by the above-mentioned pressure plate 31, and the pressure plate 31 and the rear side wall of the shell 1 are directly fixed by fasteners. The inner rod 214 can be slidably assembled in the outer rod 213 and can slide up and down relative to the outer rod 213, thereby facilitating the up and down telescopic adjustment of the pull rod body 21.

[0051] In some embodiments, the pressing plate 31 is connected and fixed to the pull rod body 21 by fasteners. The fasteners may be structural members such as screws and bolts. Both ends of the pressing plate 31 may be provided with ears, etc. The fasteners may pass through the ears and be connected to the rear side wall of the housing 1.

[0052] In some embodiments, there are multiple pressing plates 31, and the multiple pressing plates 31 are arranged at intervals along the extension direction of the pull rod body 21. For example, there may be two pressing plates 31, and the two pressing plates 31 may be arranged at intervals in the up and down directions, and each pressing plate 31 may be pressed on the outer peripheral side of the pull rod body 21 and connected and fixed to the housing 1, thereby enhancing the stability of the fixation. In some other embodiments, there may also be three, four, or other numbers of pressing plates 31.

[0053] In some embodiments, the fixing assembly 3 further includes a pull rod housing 32 , the pull rod housing 32 is fixed to the housing 1 , and the pressing plate 31 and at least a portion of the pull rod body 21 are enclosed in the pull rod housing 32 .

[0054] For example, Figure 2As shown, the material of the pull rod housing 32 can be plastic, etc., and the pull rod housing 32 can be fixed to the rear side wall of the housing 1 by fasteners such as screws, and a part of the outer rod 213 and the pressure plate 31 can be located in the pull rod housing 32. The setting of the pull rod housing 32 can improve the overall appearance on the one hand, and can prevent the pressure plate 31 from being exposed on the other hand, thereby playing a protective effect.

[0055] In some embodiments, the pull rod housing 32 and the pressing plate 31 are fixed to the housing 1 by fasteners. This facilitates the installation and removal of the pull rod housing and the pressing plate 31, and also provides convenience for subsequent maintenance and replacement.

[0056] In some embodiments, the rod housing 32 is connected and fixed to the pressure plate 31 and the rod body 21 by fasteners, and the fasteners pass through the rod housing 32, the pressure plate 31, and the rod body 21. For example, the fasteners can be long screws, which extend along the front-to-back direction and can pass through the rod housing 32, the pressure plate 31, and the outer rod 213 of the rod body 21 at the same time. Thus, the same fastener can be used to limit the position of the rod housing 32, the pressure plate 31, and the rod body 21, ensuring the consistency and accuracy of the assembly of the three.

[0057] In some embodiments, a guide rail structure 13 is provided on the side wall of the shell 1, and the extension direction of the guide rail structure 13 is consistent with the extension direction of the pull rod body 21. The middle part of the guide rail structure 13 is lower than the two sides in the width direction, and the lateral width of the pull rod body 21 does not exceed the width of the guide rail. After the pull rod body 21 is embedded in the guide rail structure, it is clamped between the guide rail structure 13 and the pressure plate 31.

[0058] For example, Figure 4 As shown, the guide rail structure 13 can be integrally formed on the rear side wall of the housing 1, and the guide rail structure 13 extends in the up-down direction. The width direction of the guide rail structure 13 and the transverse direction of the pull rod body 21 can both be left-right directions. The guide rail structure 13 can be provided with groove-shaped structures at both ends of the up-down direction, thereby making the middle of the guide rail structure 13 shorter than the left edge or the right edge of the guide rail structure 13. The width dimension of the pull rod body 21 is smaller than the width dimension of the guide rail structure 13. When the pull rod body 21 is pressed and fixed by the pressing plate 31, the outer rod 213 of the pull rod body 21 can fit with the middle of the guide rail structure 13, so that the outer rod 213 can be limited and fixed.

[0059] The provision of the guide rail structure 13 can, on the one hand, enhance the structural strength of the rear side wall of the housing 1 , and on the other hand, can be extruded and matched with the outer rod 213 , thereby enhancing the fixing effect on the outer rod 213 .

[0060] In some embodiments, the guide rail structure 13 includes two long rails 131 and multiple short rails 132. The two long rails 131 are arranged in parallel and spaced apart, and both long rails 131 extend along the extension direction of the pull rod body 21. Each short rail 132 is connected between the two long rails 131, and the multiple short rails 132 are arranged at intervals along the extension direction of the long rails 131.

[0061] For example, Figure 4 As shown, the long rail 131 and the short rail 132 can be integrally formed on the rear side wall of the housing 1, the two long rails 131 can extend in the up-down direction and can be arranged at intervals in the left-right direction, the multiple short rails 132 can extend in the left-right direction and can be arranged at equal intervals in the up-down direction, and the left end of each short rail 132 can be connected to the long rail 131 on the left, and the right end of each short rail 132 can be connected to the long rail 131 on the right. During assembly, the outer rod 213 can be pressed and fitted with the multiple short rails 132 under the action of the pressing plate 31, thereby ensuring the fixing effect of the outer rod 213.

[0062] In some embodiments, a guide rail structure 13 is disposed on the side wall of the housing 1 , and a plurality of mounting posts 14 are disposed on the housing 1 . The mounting posts 14 are disposed beside the guide rail structure 13 , and the pull rod housing 32 is connected and fixed to the mounting posts 14 .

[0063] For example, Figure 4 As shown, the mounting column 14 can be integrally formed on the rear wall of the shell 1, the mounting column 14 can be cylindrical and can extend along the front-to-back direction, a plurality of mounting columns 14 can be provided on the left and right sides of the guide rail structure 13, and each side of the guide rail structure 13 can be arranged at intervals along the up-down direction.

[0064] During assembly, the pressure plate 31 can be connected and fixed to the rear side wall of the shell 1 by fasteners, and the mounting column 14 can be inserted into the pull rod shell 32, and the pull rod shell 32 can be connected and fixed to the corresponding mounting column 14 by fasteners, thereby ensuring the stability of the fastener connection.

[0065] In some embodiments, the pull rod body 21 includes a first rod body 211 and a second rod body 212 , the free ends of the first rod body 211 and the second rod body 212 are connected via a gripping portion 22 , and the first rod body 211 and the second rod body 212 are detachably fixed via correspondingly arranged pressing plates 31 .

[0066] For example, Figure 2 As shown, the pull rod body 21 may include two relatively independent rod structures, namely a first rod 211 and a second rod 212. The first rod 211 and the second rod 212 may extend in the up-down direction and may be arranged at intervals in the left-right direction. The gripping portion 22 may be connected between the top end of the first rod 211 and the top end of the second rod 212.

[0067] The first rod body 211 and the second rod body 212 are respectively provided with two pressing plates 31 and a pull rod housing 32, so that the first rod body 211 and the second rod body 212 can be connected and fixed to the housing 1. The provision of the two rod bodies improves the overall structural strength and stability of the pull rod body 21.

[0068] In some embodiments, the power supply housing further includes a side socket 4, which is located between the first rod 211 and the second rod 212 and is disposed on the housing 1. Figure 1 As shown, the side socket 4 can be arranged on the rear side wall of the shell 1. The side socket 4 is an electrical connector, which facilitates connecting other devices to the mobile power supply and can also realize series or parallel connection between different mobile power supplies.

[0069] In some embodiments, a cover plate 41 that can be flipped open and closed is provided on the outside of the side connection socket 4. Figure 1 As shown, the cover body can be a downward flip cover, and the cover body can be assembled on the top side of the side connection socket 4 by pivoting. When not in use, the cover body can block the side connection socket 4, thereby achieving a protective effect.

[0070] In some embodiments, the power supply housing also includes two casters 5, and the two casters 5 can be detachably mounted on the housing 1. For example, a mounting portion can be integrally formed on the housing 1, and the mounting portion can be provided with a threaded hole. The axles of the two casters 5 can be threadedly assembled in the corresponding threaded holes, thereby facilitating the installation and disassembly of the casters 5.

[0071] The rod body 21 and the two casters 5 are arranged on the same side of the housing 1, and the two casters 5 are located at both ends of the lower part of the housing 1. For example, the rod body 21 and the two rubber wheels can be arranged on the rear side of the housing 1, wherein the two casters 5 can be located at the rear bottom of the housing 1, thereby improving the convenience of moving the power supply housing.

[0072] The rod body 21 is located between the two casters 5 in the width direction thereof. For example, in the left-right direction, one caster 5 can be located on the left side of the rod body 21, and the other caster 5 can be located on the right side of the rod body 21, and the two rubber wheels can be arranged substantially symmetrically with respect to the rod body 21, so that the symmetry of the power supply housing in the left-right direction can be achieved.

[0073] In some embodiments, the housing 1 includes a bottom shell 11 and a top cover 12. The bottom shell 11 is integrally formed, and the top cover 12 is detachably and sealedly assembled on the top of the bottom shell 11. Figure 1As shown, the bottom shell 11 may be in a square box shape, the material of the bottom shell 11 may be metal, the top cover 12 may be in a rectangular plate shape, and the top cover 12 may be fixed to the top of the bottom shell 11 by fasteners such as screws and seal the top opening of the bottom shell 11.

[0074] The integrated configuration of the bottom shell 11 can improve the structural strength and waterproof sealing of the bottom shell 11, and the metal material can make the bottom shell 11 have better thermal conductivity, thereby facilitating the rapid dissipation and conduction of heat to the outside.
