[0034] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more unless otherwise specifically defined.

[0035] Please refer to Figures 1 to 5, a description will now be given of an AC / DC integrated power supply housing provided by an embodiment of the present application. Refer to Figure 1 , the AC / DC integrated power supply housing includes: a bottom case 6 and an upper cover 1. An accommodation cavity for accommodating a battery 4 and a PCBA board 5 is provided inside the bottom case 6, and an opening communicating with the accommodation cavity is provided at the upper end of the bottom case 6; a connection hole 61 for connecting a power cord 9 is provided on the side surface of the bottom case 6, and the connection hole 61 communicates with the accommodation cavity; the upper cover 1 seals the opening at the upper end of the bottom case 6, and the upper cover 1 is detachably connected to the bottom case 6 through a connection structure.

[0036] In the use of the technical solution of the present application, the battery 4 and the PCBA board 5 are placed in the accommodation cavity; the PCBA board 5 is electrically connected to the battery 4; the power cord 9 is introduced from the connection hole 61 and connected to the power supply terminal on the PCBA board 5; after installation, the upper cover 1 is connected to the bottom case 6 through the connection structure. After connection, the upper cover 1 seals the opening at the upper end of the bottom case 6. Since the upper cover 1 and the bottom case 6 are detachably connected, when maintenance and repair are required, the upper cover 1 can be detached from the bottom case 6 through the connection structure, so that the upper cover 1 and the bottom case 6 are separated, exposing the opening at the upper end of the bottom case 6, and then the internal battery 4 and PCBA board 5 can be detected and repaired or replaced; the AC / DC integrated power supply can extend its service life and avoid failures or reduce the probability of failures during use.

[0037] Preferably, the connection structure includes a tab 64 provided at the upper end of the bottom case 6, and a card hole 65 is provided in the middle of the tab 64. A card block 13 cooperating with the buckle is provided at the lower end of the upper cover 1.

[0038] The connection structure realizes detachable connection through the cooperation of the card hole 65 and the card block 13; when the upper cover 1 is connected to the bottom case 6, due to the certain elasticity of the tab 64, the upper cover 1 moves towards the bottom case 6, the card block 13 first abuts against the tab 64 and pushes the tab 64 outwards, and the tab 64 undergoes elastic deformation, that is, it bends, until the card block 13 enters the card hole 65, the tab 64 resumes its original shape, and the lower end face of the upper cover 1 abuts against the end face of the upper end of the accommodation cavity of the bottom case 6, and the upper cover 1 seals the opening at the upper end of the bottom case 6.

[0039] Secondly, in order to improve the connection force between the bottom case 6 and the upper cover 1, at least two tabs 64 are provided on the upper end face of the bottom case 6, and two of the tabs 64 are distributed at both ends of the bottom case 6; card blocks 13 corresponding to the tabs 64 are respectively provided on both sides of the lower end of the upper cover 1. Preferably, the two tabs 64 are arranged oppositely. In addition to the above, the connection structure can also adopt a threaded connection structure. Bolts or screws are provided between the upper cover 1 and the bottom case 6, and the upper cover 1 and the bottom case 6 are connected through the bolts or screws.

[0040] In this embodiment, two tabs 64 are provided on opposite sides of the bottom case 6. When the upper cover 1 is connected to the bottom case 6, the clamping blocks 13 on both sides of the lower end of the upper cover 1 need to first extrude the corresponding tabs 64 of the two clamping blocks 13 outward until the clamping blocks 13 are snapped into the clamping holes 65; the two tabs 64 play a clamping role on the upper cover 1. Preferably, the two tabs 64 are arranged oppositely. After being arranged oppositely, the clamping forces of the two tabs 64 are on a straight line, and the clamping is more effective; at the same time, it also prevents the upper cover 1 from being easily disassembled relative to the bottom case 6.

[0041] Secondly, in order to facilitate the installation of the upper cover 1, a lower inclined surface or a lower arc surface for easily pushing against the tab 64 is provided at the lower end of the clamping block 13 on the upper cover 1; the design of the lower inclined surface or the lower arc surface makes the thickness of the clamping block 13 gradually increase from bottom to top. When contacting the tab 64, the lower inclined surface or the lower arc surface contacts the upper end of the tab 64 and gradually pushes the tab 64 outward, and the tab 64 is gradually deformed. Similarly, in order to facilitate the deformation of the upper end of the tab 64, an upper inclined surface or an upper arc surface is provided at the upper end of the tab 64, and the thickness of the upper end of the tab 64 gradually increases from top to bottom. When the clamping block 13 contacts the tab 64, it first contacts the upper inclined surface or the upper arc surface and gradually pushes the tab 64 outward, and the tab 64 is gradually deformed. To avoid a large sudden deformation of the tab 64, a gradually deformed structure is adopted to make the tab 64 deform gradually.

[0042] See Figure 2 、 Figure 3 and Figure 4 、 Figure 5 ; preferably, a lower thickening portion 618 is provided at the upper end of the bottom case 6, and a concave annular groove 67 or a convex ring 12 protruding upward is provided in the middle of the upper end surface of the lower thickening portion 618. An upper thickening portion 14 corresponding to the lower thickening portion 618 is provided at the lower end of the upper cover 1. A convex ring 12 extending downward or a concave annular groove 67 is provided in the middle of the lower end surface of the upper thickening portion 14 corresponding to the lower thickening portion 618. The convex ring 12 is inserted into the annular groove 67, and the upper thickening portion 14 abuts against the lower thickening portion 618.

[0043] When the upper cover 1 is connected to the bottom case 6, in addition to firm connection, the sealing performance also needs to be considered; to provide sealing performance, the upper cover 1 and the bottom case 6 respectively adopt convex and concave structures, that is, the upper cover 1 is provided with one of the convex and concave structures, and the bottom case 6 is provided with the other of the convex and concave structures; so that the abutting surface between the upper cover 1 and the bottom case 6 is not a single plane but a convex tooth surface, increasing the contact surface and the contact area, effectively improving the sealing performance; since at present, when designing and producing the power supply housing, cost needs to be considered, the wall thickness of the power supply housing is relatively small; it is difficult to produce an annular groove 67 on the original thickness; for this reason, the technical solution of this application adopts a thickening part 14 at the lower end of the upper cover 1 and a lower thickening part 618 at the upper end of the bottom case 6. In this embodiment: a convex ring 12 extending downward is provided in the middle of the lower end surface of the thickening part 14, and an inwardly concave annular groove 67 is provided in the middle of the upper end surface of the lower thickening part 618. When connecting, the upper convex ring 12 is inserted into the lower annular groove 67. Of course, another structure can also be adopted: an inwardly concave annular groove 67 is provided in the middle of the lower end surface of the thickening part 14, and an upwardly protruding convex ring 12 is provided in the middle of the upper end surface of the lower thickening part 618.

[0044] Through the insertion connection of the convex ring 12 and the annular groove 67, a detachable connection is formed; in specific settings, the convex ring 12 and the annular groove 67 form an interference fit connection or a mating connection. It can not only achieve detachable connection but also achieve sealing.

[0045] To further improve the sealing performance, preferably, a sealing ring 7 is provided in the annular groove 67. The sealing ring 7 is located between the convex ring 12 and the bottom surface of the annular groove 67. By providing the sealing ring 7, the sealing performance between the bottom case 6 and the upper cover 1 can be well increased.

[0046] See Figure 4 、 Figure 5 ; further, an inwardly concave annular groove 67 is provided in the middle of the lower thickening part 618, and a lower inner ring 68 and a lower outer ring 66 are formed on both sides of the annular groove 67. There is a height difference between the lower outer ring 66 and the lower inner ring 68. A convex ring 12 extending downward is provided at the lower end of the upper thickening part 14. An upper inner ring 15 and an upper outer ring 11 are respectively formed on both sides of the convex ring 12. There is a height difference between the upper inner ring 15 and the upper outer ring 11; when the upper cover 1 is connected to the bottom case 6, the lower inner ring 68 abuts against the upper inner ring 15, and the lower outer ring 66 abuts against the upper outer ring 11; and the latch 13 is snapped into the latching hole 65.

[0047] To further improve the sealing performance, the lower inner ring 68 and the lower outer ring 66 are set at different heights, and correspondingly, the upper inner ring 15 and the upper outer ring 11 are also set at different heights. This setting makes the inner abutting surface between the upper inner ring 15 and the lower inner ring 68 located above or below, and the outer abutting surface between the upper outer ring 11 and the lower outer ring 66 located below or above, that is, the inner abutting surface and the outer abutting surface are offset in height. In this embodiment: the lower end surface of the upper outer ring 11 is lower than the lower end surface of the upper inner ring 15, and the upper end surface of the lower outer ring 66 is lower than the upper end surface of the lower inner ring 68. Of course, it can also be: the lower end surface of the upper outer ring 11 is higher than the lower end surface of the upper inner ring 15, and the upper end surface of the lower outer ring 66 is higher than the upper end surface of the lower inner ring 68.

[0048] In this embodiment, the tab 64 is arranged on the upper end surface of the lower outer ring 66, the upper outer ring 11 is provided with a notch that cooperates with the tab 64, and the block 13 is arranged in the notch.

[0049] Arranging the tab 64 on the lower outer ring 66 and the block 13 in the notch can reduce additional designs; secondly, the block 13 can be a part of the upper outer ring 11; during the design, the periphery of the block 13 is designed as a notch, and the notch corresponds to the tab 64.

[0050] See Figures 2 to 5 ; wherein, a partition is provided in the middle of the bottom case 6, and the partition divides the accommodating cavity into a battery cavity and a PCBA cavity.

[0051] Currently, the battery 4 generally uses dry batteries. After long-term use, the battery 4 may age and leak liquid. Once leakage occurs, it will contaminate the PCBA board 5, causing damage to the electronic components on the PCBA. To protect the PCBA board 5, the technical solution of this application uses the method of separating with a partition to divide the accommodating cavity into a battery cavity and a PCBA cavity, and the two will not interfere with each other.

[0052] See Figure 3 And Figure 4 ; the middle of the partition is provided with a middle thickening part 611, and lower partition pieces 612 are formed on both sides of the middle thickening part 611; the height of the lower partition pieces 612 is higher than that of the middle thickening part 611, and a connection hole is provided on the upper end surface of the middle thickening part 611; the lower end surface of the upper cover 1 is provided with two upper partition pieces 18 arranged opposite to the lower partition pieces 612 and an upper convex block 16 arranged opposite to the middle thickening part 611. The upper convex block 16 is provided with a through hole 17 and is connected with a connecting piece 2. One end of the connecting piece 2 passes through the through hole 17 and extends into the connection hole to be connected with the middle thickening part 611.

[0053] See Figure 2 、 Figure 5;The outer end diameter of the perforation 17 is increased to form a counterbore 19. A limiting portion that mates with the counterbore 19 is provided at the end of the connecting member 2. A sealing gasket 3 is provided on the bottom surface of the counterbore 19, and the sealing gasket 3 is sleeved outside the connecting member 2.

[0054] The upper cover 1 and the bottom case 6 are only connected by plugging and buckling. When impacted by a large external force, the upper cover 1 is very likely to be separated from the bottom case 6. Therefore, it is necessary to design a connecting member 2 to connect the upper cover 1 and the bottom case 6 through the connecting member 2. The traditional connection method is to necessarily increase the thickness of the side walls of the upper cover 1 and the bottom case 6 and set the connection holes on the side wall of the bottom case 6, which will increase the cost. In this embodiment, the connecting member 2 can be a bolt, the connection hole is a threaded hole, and the bolt can be installed with the aid of a partition, which can avoid increasing a large cost. By providing a thickening portion in the middle of the partition, a threaded hole is formed in the middle of the thickening portion. A perforation 17 is provided in the middle of the upper cover 1. One end of the bolt passes through the perforation 17, extends into the threaded hole and is threadedly connected to the thickening portion. Through the connection of the bolt, the upper cover 1 and the bottom case 6 are connected as a whole.

[0055] Secondly, to prevent the head of the bolt from protruding from the surface of the upper cover 1, a counterbore 19 is formed at the outer end of the perforation 17, and the head of the bolt is hidden in the counterbore 19. Secondly, considering the sealing requirement of the upper cover 1, a sealing gasket 3 is provided in the counterbore 19, and the sealing gasket 3 is sleeved outside the bolt.

[0056] Preferably, a positioning counterbore is provided at the upper end of the threaded hole. The upper convex block 16 extends downward to form an upper positioning convex ring, and the upper positioning convex ring is inserted into the positioning counterbore.

[0057] After the positioning counterbore and the upper positioning convex ring are provided, when installing the upper cover 1 on the bottom case 6, it can be first positioned by the preliminary insertion of the upper positioning convex ring and the positioning counterbore, and then the upper cover 1 is squeezed towards the bottom case 6. The latch 13 of the upper cover 1 is latched with the latch hole 65 on the lower cover tab 64. Finally, threaded connection is performed through the bolt.

[0058] Furthermore, the lower spacer 612 is provided with a notch 617 for installing an electrical contact piece.

[0059] Since the battery cavity and the PCBA cavity are separated by a partition, and the battery in the battery cavity needs to be electrically connected to the PCBA board 5 in the PCBA cavity through a wire. Therefore, the technical solution of this application provides a notch 617 for installing an electrical contact piece at the upper end of the lower spacer 612. During specific installation, a plurality of electrical contact pieces are provided in the battery cavity. The plurality of electrical contact pieces are used to connect the internal batteries in series or in parallel. One end of two of the electrical contact pieces respectively passes through the corresponding notch 617 and is bent to form a latching end, and the latching end is electrically connected to the PCBA board 5 in the PCBA cavity.

[0060] See Figure 3 、Figure 4 and Figure 5 A partition block for isolating adjacent batteries is provided in the battery chamber; preferably, the partition block includes a hollow cylinder 619 in the middle, and a plurality of evenly distributed isolation sheets 69 are provided on the side surface of the hollow cylinder 619.

[0061] In specific use, multiple batteries may be used in the battery chamber. To prevent adjacent batteries from being too close and interfering with each other due to heat generation during operation, a partition block is provided in the battery chamber to preliminarily isolate the batteries. In this embodiment, when applied, 4 dry batteries are installed in the battery chamber. For convenient isolation, the partition block includes a hollow cylinder 619 in the middle, and 4 evenly distributed isolation sheets 69 are provided on the side surface of the hollow cylinder 619. The 4 isolation sheets 69 roughly divide the battery chamber into 4 single-battery spaces for accommodating batteries, and the batteries are respectively installed and fixed in the 4 single-battery spaces.

[0062] Furthermore, a set of card strips 616 for fixing the PCBA board 5 are respectively provided on two corresponding side walls of the PCBA chamber. The set of card strips 616 includes two parallel card strips 616, and a card slot 615 for clamping with the PCBA board 5 is formed between the two card strips 616.

[0063] To conveniently fix the PCBA board 5 in the PCBA chamber, the technical solution of this application provides a set of card strips 616 on two corresponding side walls of the PCBA chamber. When installing the PCBA board 5, both sides of the PCBA board 5 are inserted into the card slots 615 of the two sets of card strips 616; thereby, both sides of the PCBA board 5 are limited and fixed.

[0064] Preferably, another side wall of the PCBA chamber is provided with an abutting plate 614 for abutting against the PCBA board 5. The lower end surface of the upper cover 1 is provided with a downwardly extending abutting block, and the abutting block includes a first abutting section 110 for abutting against the abutting plate 614 and a second abutting section 111 for abutting against the PCBA board 5.

[0065] To further fix the PCBA board 5, the technical solution of this application also provides an abutting plate 614. The abutting plate 614 faces the surface of the PCBA board 5. When specifically arranged, the abutting plate 614 can be Z-shaped or the like to avoid some structures; secondly, an abutting block is provided on the upper cover 1. After the upper cover 1 is installed, the two sections of the abutting block respectively abut against the abutting plate 614 and the PCBA board 5 to realize the fixation of the PCBA board 5.

[0066] Embodiment 2: An AC / DC integrated power supply includes the above-mentioned AC / DC integrated power supply housing, and a battery and a PCBA board 5 are provided in the accommodating chamber.

[0067] See Figure 2 、 Figure 3 、 Figure 5; The connection hole 61 is connected to a power cord 9. The power cord is provided with an SR wire head. A waterproof ring 91 is connected to one slot of the SR wire head and sleeved in the connection hole 61, and is in fit connection with the connection hole 61; the inner end of the SR wire head extends into the bottom case 6 and the inner end of the SR wire head has an annular slot 93. A card 8 is clamped in the annular slot 93, and the card 8 abuts against the inner side surface of the bottom case 6; a protrusion 92 is provided on the side surface of the other end of the waterproof ring 91. An inner convex ring 63 extends outward from the side wall of the connection hole 61, and a concave hole 62 that mates with the protrusion 92 is provided on the inner side surface of the inner convex ring 63. The protrusion 92 is inserted into the concave hole 62.

[0068] When the bottom case 6 is in use, the power cord 9 needs to pass through the connection hole 61 and extend into the PCBA cavity to be connected to the PCBA board 5. Therefore, waterproof treatment needs to be carried out on the power cord 9. In this embodiment, a waterproof ring 91 is formed on the outside of the power cord 9. When one end of the power cord 9 extends into the bottom case 6, the waterproof ring 91 is sleeved with the connection hole 61, preferably in an interference fit connection or a fit connection; secondly, in order to prevent the power cord 9 from detaching and the waterproof ring 91 from leaving the connection hole 61 during use; it is necessary to limit the waterproof ring 91. In this technical solution, a protrusion 92 is provided at the outer end of the waterproof ring 91. An inner convex ring 63 extends outward from the side wall of the connection hole 61, and a concave hole 62 is provided on the inner side surface of the inner convex ring 63. The protrusion 92 is inserted into the concave hole 62. An extension part is provided on the inner side of the waterproof ring 91, and an annular slot 93 is provided on the extension part. The annular slot 93 is clamped with the card 8; preferably, the card 8 is U-shaped, and the two sides of the waterproof ring 91 are clamped by the U-shaped card 8 and the protrusion 92 to keep it in the connection hole 61.

[0069] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
