Description

Technical Field

[0001] The utility model belongs to the technical field of power supply, and more specifically relates to a stacked power supply. Background Art

[0002] A general power supply product usually has one end connected to the AC power grid and one end providing an output interface to power the device. When multiple power supplies are needed to power multiple devices, each power supply needs to be connected to the AC power grid through a socket, and then the output port of the power supply is used to power different devices.

[0003] Since a single power supply has limited output ports and limited expansion capabilities, when the number of output interfaces required to be provided by the power supply exceeds the upper limit of the designed output ports of a single power supply, the number of power supplies needs to be increased to meet the power supply demand, and the number of AC sockets that users need to provide for the power supply needs to be increased accordingly. At this time, if the number of available sockets near the power supply is insufficient, it is necessary to add mobile sockets to power multiple power supplies. In other words, multiple power supplies need to be used to connect the corresponding devices separately, and even additional sockets need to be used to connect the power supply, resulting in too many power supplies and sockets, and the power cords are messy, making it difficult to layout and repair. Utility Model Content

[0004] The purpose of the embodiments of the utility model is to provide a stacked power supply to solve the technical problem in the prior art that a large number of power supplies and messy power lines cause difficulty in layout and maintenance.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: to provide a stacked power supply, including a plurality of power supply structures arranged in sequence, wherein the power supply structure includes a power supply body and a power cord connected to the power supply body, the end of the power cord has a plug, and the power supply body has a socket and an output port for an external device, wherein the plug of one of the power supply structures is used to be plugged into the socket of an adjacent power supply structure, and the two adjacent power supply structures are connected to each other via a connecting structure.

[0006] In the above scheme, the stacked power supply includes multiple power supply structures, and two adjacent power supply structures are connected to each other through a connecting structure, so that the multiple power supply structures form a whole, which is convenient for layout and installation. The plug of one power supply structure is plugged into the jack of the adjacent power supply structure, so that each power supply structure is electrically connected, the power cord is plugged in in order, and the wiring is neater. At the same time, the power supply structure is provided with an output port connected to an external device, and the output port is used to supply power to the external device or transmit data.

[0007] Optionally, the surfaces where the two power supply structures contact each other are first side surfaces, and the connection structure is arranged at the two first side surfaces that contact each other.

[0008] In the above solution, when two adjacent power supply structures are connected to each other, the two first side surfaces are in contact with each other, and the connection structure is hidden between the two first side surfaces, so that the exposed surface of the stacked structure is neater and smoother.

[0009] Optionally, the connection structure includes a dovetail groove and a dovetail block that cooperate with each other, wherein one of the first side surfaces has the dovetail groove, and the other of the first side surfaces has the dovetail block.

[0014] In the above solution, the two insertion parts are respectively extended into the slot parts of two adjacent second side surfaces, so that the two power supply structures can be connected through the connecting piece.

[0015] Optionally, a first clamping portion is provided on the insertion portion, and a second clamping portion is provided on the slot portion, and the first clamping portion and the second clamping portion are clamped and matched with each other.

[0016] In the above scheme, when the insertion portion of the connecting member extends into the slot portion of the second side, the first clamping portion and the second clamping portion are clamped with each other, and the constraint direction of the first clamping portion and the second clamping portion is the plugging direction of the insertion portion and the slot portion. Under the clamping action of the first clamping portion and the second clamping portion, the insertion portion will not fall out of the slot portion, so that the two adjacent power supply structures are constrained in multiple directions, thereby making the connection between the two power supply structures more stable.

[0017] Optionally, an anti-slip portion is provided on the surface of the slot portion and / or the insertion portion.

[0018] In the above solution, the anti-slip portion is used to make the inner wall of the slot portion and the insertion portion abut against each other, thereby increasing the friction between the slot portion and the insertion portion and making the connection between the connector and the power structure more stable.

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0037] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0039] A general power supply product usually has one end connected to the AC power grid and one end providing an output interface to power the device. When multiple power supplies are needed to power multiple devices, each power supply needs to be connected to the AC power grid through a socket, and then the output port of the power supply is used to power different devices.

[0040] Since a single power supply has limited output ports and limited expansion capabilities, when the number of output interfaces required to be provided by the power supply exceeds the upper limit of the designed output ports of a single power supply, the number of power supplies needs to be increased to meet the power supply demand, and the number of AC sockets that users need to provide for the power supply needs to be increased accordingly. At this time, if the number of available sockets near the power supply is insufficient, it is necessary to add mobile sockets to power multiple power supplies. In other words, multiple power supplies need to be used to connect the corresponding devices separately, and even additional sockets need to be used to connect the power supply, resulting in too many power supplies and sockets, and the power cords are messy, making it difficult to layout and repair.

[0041] In order to solve the above technical problems, an embodiment of the utility model proposes a stacked power supply, which includes a plurality of power supply structures arranged in sequence, and two adjacent power supply structures are connected to each other through a connecting structure, so that the multiple power supply structures are connected into a whole, which is convenient for installation and has a neater layout. In two adjacent power supply structures, the plug of one power supply structure is used to plug into the socket of the adjacent power supply structure, so that the two adjacent power supply structures are electrically connected, and the power cords are distributed in sequence through the connection between the plug and the socket, and the layout is neat. When the number of output ports of a single power supply structure is insufficient, the stacked power supply can be used to provide more output ports. The stacked power supply has a stable structure, is easy to lay out, and the power cords are neatly arranged.

[0042] The stacked power supply provided by the embodiment of the utility model is now described.

[0043] Please also read Figures 1 to 7 The stacked power supply includes a plurality of power supply structures 10, and the plurality of power supply structures 10 are arranged in sequence, which can be understood as being arranged in a column in a predetermined direction. Two adjacent power supply structures 10 are connected to each other through a connection structure 114, so that the two adjacent power supply structures 10 are mutually constrained at least in the above-mentioned predetermined direction. In this way, the plurality of power supply structures 10 are connected in sequence to form a whole, which is convenient for the overall installation and layout of the stacked power supply, and the arrangement of the plurality of power supply structures 10 is also relatively neat, which is convenient for the subsequent maintenance, replacement, etc. of the power supply structures 10.

[0044] The power supply structure 10 includes a power supply body 11 and a power cord 12. The power supply body 11 has a jack 115 and an output port 116. The output port 116 is used to connect to an external device to supply power to the external device or transmit data. The jack 115 is used to be plugged into a plug 13. Specifically, one end of the power cord 12 is connected to the power supply body 11, and the other end of the power cord 12 is a plug 13. In two adjacent power supply structures 10, the plug 13 of one power supply structure 10 is used to be plugged into the jack 115 of the adjacent power supply structure 10. According to this connection method, multiple power supply structures 10 are electrically connected in sequence through the plugging method of the plug 13 and the jack 115, and the remaining plug 13 is plugged into an external AC socket. For example, the number of power supply structures 10 is three. When the stacked power supply is used, the plug 13 of the first power supply structure 10 is connected to an external AC socket, the plug 13 of the second power supply structure 10 is inserted into the socket 115 of the first power supply structure 10, and the plug 13 of the third power supply structure 10 is inserted into the socket 115 of the second power supply structure 10. It should be noted that the plugging of the plug 13 and the socket 115 enables two adjacent power supply structures 10 to be connected in parallel, so that external devices can be stably powered.

[0045] A single power supply structure 10 can be used alone. When the single power supply structure 10 is used alone, the plug 13 of the power supply structure 10 is connected to an external AC socket, and the external device is connected to the output port 116 of the power supply structure 10 .

[0046] However, since the number of output ports 116 on each power structure 10 is limited, when a large number of external devices need to be connected, the number of output ports 116 of a single power structure 10 is insufficient. Therefore, the stacked power supply provided in this embodiment can be used to expand the output ports 116, so that more external devices can be connected without causing the power cord 12 and the power structure 10 to be distributed in a messy manner, making the wiring space tidy.

[0047] The stacked power supply in the above embodiment includes a plurality of power supply structures 10, and two adjacent power supply structures 10 are connected to each other through a connection structure 114, so that the plurality of power supply structures 10 form a whole, which is convenient for layout and installation. The plug 13 of one power supply structure 10 is plugged into the jack 115 of the adjacent power supply structure 10, so that the various power supply structures 10 are electrically connected, the power cords 12 are plugged in in an orderly manner, and the wiring is neater. At the same time, the power supply structure 10 is provided with an output port 116 connected to an external device, and the output port 116 is used to supply power to the external device or transmit data.

[0048] In some embodiments of the present invention, please refer to Figure 2 , Figure 4 and Figure 7When multiple power supply structures 10 are arranged in sequence, two adjacent power supply structures 10 have surfaces in contact with each other, which are called first side surfaces 111 of the power supply structure 10. Since both sides of a power supply structure 10 may contact other power supply structures 10, both sides are called first side surfaces 111. When multiple power supply structures 10 are arranged in sequence, the sides of two adjacent power supply structures 10 located in the same plane are second side surfaces 112. In the same power supply structure 10, there are two second side surfaces 112, which are arranged parallel to each other.

[0049] In some embodiments, the power structure 10 is in a rectangular parallelepiped shape, the power structure 10 has six surfaces, and the remaining two side surfaces are third side surfaces 113 .

[0050] Since the two first side surfaces 111 are close to each other in the stacked power supply, the connection of the power cord 12, the jack 115 and the output port 116 can be arranged on the second side surface 112 or the third side surface 113, and the arrangement position is not limited here.

[0051] In some embodiments of the present invention, please refer to Figure 1 and Figure 2 The connection structure 114 is disposed at two mutually contacting first side surfaces 111. When two adjacent power supply structures 10 are connected to each other, the two first side surfaces 111 are in contact with each other, and the connection structure 114 is hidden between the two first side surfaces 111, making the exposed surface of the stacking structure neater and smoother.

[0052] In some embodiments, see Figure 1 and Figure 2 The connection structure 114 includes a dovetail groove 1142 and a dovetail block 1141 connected to each other. In two adjacent first side surfaces 111, one of the first side surfaces 111 has a dovetail groove 1142, and the other first side surface 111 has a dovetail block 1141. Through the mutual cooperation of the dovetail groove 1142 and the dovetail block 1141, the two adjacent power supply structures 10 are constrained to each other at least in a direction perpendicular to the length direction of the dovetail groove 1142.

[0053] The cross-sections of the dovetail groove 1142 and the dovetail block 1141 are both trapezoidal, and the side of the trapezoid close to the first side surface 111 is the top side (the side with the smaller length), so that the two power supply structures 10 are mutually constrained in the direction perpendicular to the length direction of the dovetail groove 1142. The connection mode of the dovetail groove 1142 and the dovetail block 1141 is equivalent to the sliding connection and cooperation of the two power supply structures 10, and the sliding direction is parallel to the length direction of the dovetail groove 1142, that is, the power supply structure 10 can only move in the direction parallel to the length direction of the dovetail groove 1142, and is mutually constrained with the adjacent power supply structure 10 in other directions.

[0054] In the same power supply structure 10, one of the first side surfaces 111 has a dovetail groove 1142, and the other first side surface 111 has a dovetail block 1141, so that the two first side surfaces 111 of the power supply structure 10 are respectively connected to the other two power supply structures 10 to form a stacked power supply in which multiple power supply structures 10 are connected in sequence.

[0055] Specifically, when installing a stacked power supply, the bottom of one power supply structure 10 is aligned with the top of another power supply structure 10, and then the dovetail block 1141 is inserted into the dovetail groove 1142 to connect the two power supply structures 10. According to the above method, a stacked power supply composed of multiple power supply structures 10 can be installed.

[0056] In some embodiments of the present invention, please refer to Figures 3 to 7 , the connection structure 114 is disposed at two adjacent second side surfaces 112. When the connection structure 114 is disposed at the second side surface 112, the second side surface 112 can be disposed close to the mounting surface, thereby hiding and shielding the connection structure 114, making the exposed surface of the stacking structure neater and smoother.

[0057] In some embodiments, see Figures 3 to 7 The connection structure 114 includes a connection member 1143 and a slot portion 1144 disposed on the second side surface 112. Two adjacent power supply structures 10 are connected to each other through the connection member 1143, and the slot portions 1144 are disposed on the two adjacent second side surfaces 112 for cooperating with the connection member 1143. The connection member 1143 has two insertion portions 11432, and the two insertion portions 11432 are respectively extended into the slot portions 1144 of the two adjacent second side surfaces 112, so that the two power supply structures 10 can be connected through the connection member 1143.

[0058] Optionally, the insertion portion 11432 and the slot portion 1144 are interference-fitted, so that after the connector 1143 is installed on the two power supply structures 10, the connector 1143 is not easily removed from the power supply structure 10 when no external force is applied. In order to increase the static friction between the insertion portion 11432 and the slot portion 1144, at least one of the insertion portion 11432 and the slot portion 1144 may be made of silicone, rubber or the like.

[0059] In some embodiments, the insertion portion 11432 is provided with a first clamping portion 11433, and the slot portion 1144 is provided with a second clamping portion 11441, and the first clamping portion 11433 and the second clamping portion 11441 are clamped and matched with each other. When the insertion portion 11432 of the connector 1143 extends into the slot portion 1144 of the second side surface 112, the first clamping portion 11433 and the second clamping portion 11441 are clamped with each other, and the constraint direction of the first clamping portion 11433 and the second clamping portion 11441 is the plugging direction of the insertion portion 11432 and the slot portion 1144. Under the clamping action of the first clamping portion 11433 and the second clamping portion 11441, the insertion portion 11432 will not fall out of the slot portion 1144, so that the two adjacent power supply structures 10 are constrained in multiple directions, thereby making the connection between the two power supply structures 10 more stable.

[0060] Optionally, the insertion portion 11432 and the slot portion 1144 are both strip-shaped, so that the matching area between the insertion portion 11432 and the slot portion 1144 is larger, thereby enhancing the stability of the connection between two adjacent power supply structures 10.

[0061] Optionally, the first clamping portion 11433 may be disposed on one side of the insertion portion 11432 or on both sides of the insertion portion 11432. The second clamping portion 11441 may be disposed on one side of the slot portion 1144 or on both sides of the slot portion 1144.

[0062] Optionally, the number of the first clamping portions 11433 is one or more, and correspondingly, the number of the second clamping portions 11441 is one or more.

[0063] See also Figure 4 and Figure 5 One of the first clamping portion 11433 and the second clamping portion 11441 is a convex structure, and the other is a concave structure. The convex direction of the convex structure and the concave direction of the concave structure are both set at an angle to the plugging direction of the insertion portion 11432 and the slot portion 1144, such as vertically.

[0064] Optionally, the raised structure is a convex point, and the concave structure is a concave pit. The shape of the convex point and the concave pit can be hemispherical, so that when the insertion portion 11432 and the slot portion 1144 are plugged into each other, the plugging is smoother and the inner wall of the slot portion 1144 will not be scratched. The convex point and the concave pit can also be other shapes, which are not limited here. The connection between the connector 1143 and two adjacent power supply structures 10 can be achieved by the mutual engagement of the convex point and the concave pit.

[0065] Optionally, the protruding structure is a buckle, and the recessed structure is a slot, and the connection between the buckle and the slot can also be achieved by the mutual engagement of the buckle and the slot to achieve the connection between the connector 1143 and two adjacent power supply structures 10 .

[0066] Optionally, the protruding structure is a convex strip, and the concave structure is a strip-shaped groove. The length direction of the convex strip and the length direction of the strip-shaped groove may be parallel to the length direction of the insertion portion 11432.

[0067] In some embodiments of the present invention, the surface of the slot portion 1144 and / or the insertion portion 11432 is provided with an anti-slip portion, specifically including the following three situations: the inner wall of the slot portion 1144 is provided with an anti-slip portion; or the surface of the insertion portion 11432 is provided with an anti-slip portion; or the inner wall of the slot portion 1144 and the surface of the insertion portion 11432 are both provided with an anti-slip portion. The anti-slip portion is used to make the inner wall of the slot portion 1144 and the insertion portion 11432 abut against each other, increase the friction between the slot portion 1144 and the insertion portion 11432, and make the connection between the connector 1143 and the power supply structure 10 more stable.

[0068] Optionally, the anti-slip portion is a structure such as anti-slip bumps, anti-slip patterns, and anti-slip silicone sheets.

[0069] In some embodiments of the present invention, please refer to Figures 3 to 5 , the length of the slot portion 1144 is equal to the length of the insertion portion 11432, so that the slot portion 1144 and the insertion portion 11432 are mutually adapted in the length direction. For the convenience of description, the mutual plugging direction of the insertion portion 11432 and the slot portion 1144 is referred to as the insertion direction. In this embodiment, the insertion portion 11432 can only be inserted into the slot portion 1144 along the insertion direction.

[0070] Optionally, when the first clamping portion 11433 and the second clamping portion 11441 are point-shaped or block-shaped structures, the insertion portion 11432 is inserted into the slot portion 1144 along the insertion direction, and the insertion stroke is shorter, making it easier to achieve mutual connection between the insertion portion 11432 and the slot portion 1144.

[0071] In some embodiments of the present invention, please refer to Figure 6 and Figure 7 , at least one end of the slot portion 1144 extends to the edge of the power structure 10, the length of the insertion portion 11432 is less than or equal to the length of the slot portion 1144, and when connecting two power structures 10, the connecting member 1143 can be gradually inserted into the slot portion 1144 from one end of the power structure 10 along a direction parallel to the second side surface 112.

[0072] Optionally, in a cross section perpendicular to the second side surface 112, the extending directions of the slot portion 1144 and the insertion portion 11432 are perpendicular to the second side surface 112, which can also be understood as the insertion portion 11432 being perpendicularly inserted into the slot portion 1144 relative to the second side surface 112. In this embodiment, when installing the connector 1143, the connector 1143 can be inserted into the slot portion 1144 along the insertion direction (perpendicular to the second side surface 112), or can be gradually inserted into the slot portion 1144 from one end of the power structure 10 along a direction parallel to the second side surface 112.

[0073] Optionally, in a cross section perpendicular to the second side surface 112, the extending direction of the slot portion 1144 and the insertion portion 11432 is set at an acute angle to the second side surface 112, so that the connector 1143 and the power structure 10 can be constrained in the insertion direction (perpendicular to the second side surface 112), and the connector 1143 will not fall off from the power structure 10 along the insertion direction, making the connection between two adjacent power structures 10 more stable. In this embodiment, when installing the connector 1143, it can be gradually inserted into the slot portion 1144 from one end of the power structure 10 in a direction parallel to the second side surface 112.

[0074] Optionally, in a cross section perpendicular to the second side surface 112 , the two insertion portions 11432 may be arranged in an eight-shaped shape, so that the force on the connecting member 1143 is more balanced and the possibility of the connecting member 1143 being broken or damaged is reduced.

[0075] In some embodiments of the present invention, please refer to Figure 5 , the connector 1143 further includes a connecting plate 11431, and the two inserting parts 11432 are fixedly connected to the connecting plate 11431. It can be understood that the inserting part 11432 is formed by extending from the surface of the connecting plate 11431. The connecting plate 11431 is provided to connect the two inserting parts 11432, so that the connector 1143 is integrated, which facilitates the installation of the connector 1143. In other embodiments, the connector 1143 further includes a connecting rib, which is used to connect the two inserting parts 11432.

[0076] In some embodiments of the present invention, please refer to Figure 2 and Figure 4 The output port 116, the connection between the power supply body 11 and the power cord 12, and the jack 115 can be respectively arranged on different sides of the power supply body 11, so that the internal structure of the power supply body 11 is easier to layout.
