Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic access control technology, specifically to a power supply housing, an access control power supply, and an access control system. Background Technology
[0002] Access control power supplies typically protect PCB modules, batteries, and other structures with a power supply housing. Common access control power supplies use a one-piece, sealed housing, which can only be replaced, resulting in waste. Alternatively, an opening is made at the top of the housing, and multiple screws are tightened to fit a top plate or other structure into the opening to form a sealed space. When maintenance is needed, the screws must be loosened and removed to open the housing, which is cumbersome. Repeated screw removal can strip the screws, affecting the housing's reliable closure and protective performance, and shortening its lifespan. Furthermore, repairing the internal structure requires removing it from the housing, a multi-step and time-consuming process, especially in space-constrained or fast-response scenarios (such as access control system malfunctions), leading to inefficiency.

[0057] Example 1
[0058] Please see Figure 1 , Figure 1 This is a schematic diagram of the power supply housing of this utility model, as shown below. Figure 2 As shown, the power supply housing includes: an upper housing 1, a lower housing 2, and at least one connecting shaft 3. The upper housing 1 includes an upper base plate 11 and a first upper side plate 12 and a second upper side plate 13 disposed on opposite sides of the upper base plate 11. The lower housing 2 includes a lower base plate 21 and a first lower side plate 22 and a second lower side plate 23 disposed on opposite sides of the lower base plate 21. When the upper housing 1 and the lower housing 2 are closed, the first upper side plate 12, the second upper side plate 13, the first lower side plate 22, the second lower side plate 23, the upper base plate 11, and the lower base plate 21 form a space to accommodate the PCB module and battery of the access control power supply. An input through hole 26 for electrical connection between the external power supply and the access control power supply is provided on the second lower side plate 23, and an output through hole 27 for electrical connection between the access control power supply and various devices in the access control system is provided on the first lower side plate 22. The inner side of the lower base plate 21 is fixedly connected to the PCB module and the battery. Figure 3 As shown, the first end 121 of the first upper side plate 12 and the second end 131 of the second upper side plate 13 are rotatably connected to the first lower side plate 22 via the connecting shaft 3, so that the upper housing 1 can be flipped open and closed relative to the lower housing 2; the third end 122 of the first upper side plate 12 and the fourth end 132 of the second upper side plate 13 are both provided with a snap-fit part, and the second lower side plate 23 is provided with a mating part 24. When the upper housing 1 and the lower housing 2 are in the closed state, the snap-fit part is embedded in the mating part 24 to form a fixed lock.
[0059] When the upper housing 1 and the lower housing 2 are closed, the first lower side plate 22 and the second lower side plate 23 are located between the first upper side plate 12 and the second upper side plate 13. During the opening process of the upper housing 1 and the lower housing 2, the upper housing 1 rotates relative to the first lower side plate 22 around the axis of the connecting shaft 3, and the second lower side plate 23 is located between the first upper side plate 12 and the second upper side plate 13, ensuring that the upper housing 1 and the lower housing 2 can be fully opened, so that the internal structure of the access control power supply is fully exposed.
[0060] In one implementation, such as Figure 3 As shown, the power supply housing includes a connecting shaft 3. The first lower side plate 22 and the connecting shaft 3 located between the first upper side plate 12 and the second upper side plate 13 are fixedly connected. The two ends of the connecting shaft 3 are connected to the first upper side plate 12 and the second upper side plate 13, respectively. In this implementation, the first upper side plate 12, the second upper side plate 13 and the first lower side plate 22 are connected by a connecting shaft 3, ensuring that the first upper side plate 12 and the second upper side plate 13 are absolutely synchronized during the opening and closing process.
[0061] In one implementation, such as Figure 2 As shown, the power supply housing includes two connecting shafts 3. The first upper side plate 12 and the second upper side plate 13 are respectively connected to one side of the first lower side plate 22 through a connecting shaft 3. The first connecting shaft 3 passes through the first end 121 of the first upper side plate 12 and is connected to the first lower side plate 22; the second connecting shaft 3 passes through the second end 131 of the second upper side plate 13 and is connected to the first lower side plate 22, so that the upper housing 1 can be flipped open and closed with the two shafts as fulcrum, which improves the connection strength between the upper housing 1 and the lower housing 2, and at the same time, avoids the connecting shaft 3 being placed inside the power supply housing and obstructing the installation of internal electrical components.
[0062] The third end 122 of the first upper side plate 12 and the fourth end 132 of the second upper side plate 13 are both provided with a snap-fit part. The corresponding second lower side plate 23 is provided with a mating part 24 on both sides near the first upper side plate 12 and the second upper side plate 13. A snap-fit part and a mating part 24 are snap-fitted together to form a fixed lock, so as to prevent the upper housing 1 and the lower housing 2 from opening due to shaking or accidental contact during the use of the access control power supply.
[0063] like Figure 2 and Figure 3 As shown, multiple limiting brackets 25 are provided on the inner side of the lower base plate 21. One end of the limiting bracket 25 is fixedly connected to the inner side of the lower base plate 21, and the other end extends outward from the inner side of the lower base plate 21 with a protrusion 17. A screw hole is provided at the end of the limiting bracket 25 away from the inner side of the lower base plate 21. Various components such as PCB modules and batteries are fixed on one or more limiting brackets 25 by screws to prevent the PCB modules, batteries and other components from shaking on the lower housing 2 and to ensure the connection stability of the PCB modules, batteries and other components on the lower base plate 21.
[0064] In one implementation, the limiting frame 25 is integrally formed from the lower base plate 21 by stamping and cutting. The limiting frame 25 includes a root end 251 connected to the inner side of the lower base plate 21 and a suspended end 252 extending away from the inner side of the lower base plate 21. The two root ends 251 are spaced apart. The PCB module can be fixed in the space between adjacent limiting frames 25 or installed above multiple suspended ends 252. A connection hole 253 is provided in the suspended end 252. The PCB module and the limiting frame 25 are connected and fixed by passing a strip through the connection hole 253.
[0065] In this embodiment, the first end 121 of the first upper side plate 12 and the second end 131 of the second upper side plate 13 are connected to the first lower side plate 22 via the connecting shaft 3. The third end 122 of the first upper side plate 12 and the fourth end 132 of the second upper side plate 13 are provided with snap-fit parts for engaging with the mating parts 24 on the second lower side plate 23 to prevent the upper housing 1 and the lower housing 2 from opening due to external shaking or accidental contact, thus ensuring the protective performance of the power supply housing.
[0066] like Figure 2 As shown, the input through hole 26 and the output through hole 27 are respectively provided with the corresponding second lower side plate 23 and first lower side plate 22, which avoids the movement of the wires during the opening of the power supply housing and ensures the stable connection of the wires. At the same time, the wires, the input through hole 26, the output through hole 27, the PCB module, and the battery are all centrally installed on the lower housing 2, which improves the functional integration of the lower housing 2 in the access control power supply.
[0067] In one implementation, such as Figure 3 As shown, the first lower side plate 22 includes a first body 222 and first connecting plates 221 disposed on both sides of the first body 222; the second lower side plate 23 includes a second body 232 and second connecting plates 231 disposed on both sides of the second body 232; the first connecting plates 221 and the second connecting plates 231 are located between the first body 222 and the second body 232, and the sides of the first connecting plates 221 and the second connecting plates 231 are parallel to the sides of the first upper side plate 12 and the second upper side plate 13; the connecting shaft 3 is connected to the first connecting plate 221; and the mating part 24 is disposed on the second connecting plate 231.
[0068] The first body 222 and the second body 232 are rectangular vertical plates. A first connecting plate 221 is provided on each of the two sides of the first body 222. One first connecting plate 221 is connected to the first end 121 of the first upper side plate 12 by a connecting shaft 3. The other first connecting plate 221 is connected to the second end 131 of the second upper side plate 13 by a connecting shaft 3, which simplifies the connection between the upper shell 1 and the lower shell 2. At the same time, shaft connections are provided on both sides of the first body 222 to ensure the connection stability between the upper shell 1 and the lower shell 2.
[0069] Second connecting plates 231 are respectively provided on both sides of the second body 232. The second connecting plates 231 are parallel to the first upper side plate 12 and the second upper side plate 13. Each second connecting plate 231 is provided with a mating part 24. The mating part 24 of one first connecting plate 221 mates with the snap-fit part of the third end 122 of the first upper side plate 12, and the mating part 24 of the other first connecting plate 221 mates with the snap-fit part of the fourth end 132 of the second upper side plate 13. By using two mating parts 24 and two snap-fit parts on both sides, the fixing and locking effect when the upper shell 1 and the lower shell 2 are in the closed state is further improved.
[0070] By setting the first connecting plate 221 and the second connecting plate 231, the upper shell 1 and the lower shell 2 can be stably connected. At the same time, the thickness of the first lower side plate 22 and the second side plate is avoided to ensure that the upper shell 1 and the lower shell 2 are lightweight, easy to handle and install.
[0071] The second body 232 has an input through hole 26, and the first body 222 is parallel to the second body 232 and has an output through hole 27. The first body 222 and the first connecting plate 221, and the second body 232 and the second connecting plate 231 are all integrally stamped and bent, which makes the structure of the first lower side plate 22 and the second lower side plate 23 simple, and the installation and disassembly of the upper shell 1 and the lower shell 2 convenient.
[0072] In one implementation of this embodiment, such as Figure 4 and Figure 5 As shown, elongated guide rails 15 are provided on the inner sides of the first upper side plate 12 and the second upper side plate 13, and the length direction of the guide rails 15 is parallel to the horizontal plane; as shown... Figure 6 and Figure 7 As shown, the guide rail 15 includes a first channel 151 and a second channel 151 communicating with the first channel 151. The second channel 151 has an opening on the side away from the first channel 151 for the connecting shaft 3 to be inserted. The connecting shaft 3 is inserted into the second channel 151 through the opening and extends into the first channel 151. The end of the connecting shaft 3 located in the first channel 151 has a radial flange 31. The inner diameter of the first channel 151 is larger than the radial dimension of the radial flange 31, and the radial dimension of the radial flange 31 is larger than the inner diameter of the second channel 151.
[0073] The length of the guide rail 15 is parallel to the horizontal plane. The connecting shaft 3 and the lower housing 2 are fixedly connected. When it is necessary to open the upper housing 1 and the lower housing 2, an external force is applied to the upper housing 1 to make the upper housing 1 and the lower housing 2 move relative to each other in the horizontal direction. The long guide rail 15 allows the upper housing 1 to move relative to the lower housing 2 in the horizontal plane, so that the locking part of the third end 122 of the first upper side plate 12 and the locking part of the fourth end 132 of the second upper side plate 13 are unlocked from the mating part 24 on the second connecting plate 231. After unlocking the connection between the locking part and the mating part 24, the power supply housing can be opened by flipping the upper housing 1 and the lower housing 2.
[0074] The connecting shaft 3 is fixedly connected to the first connecting plate 221. The connecting shaft 3 is slidably connected to the first upper side plate 12 and the second upper side plate 13 via the guide rail 15, so as to lock and unlock the locking part of the third end 122 of the first upper side plate 12 and the fourth end 132 of the second upper side plate 13 with the mating part 24 on the second connecting plate 231. This not only avoids the problem of accidental opening of the power supply housing when it is closed, but also further simplifies the operation of opening the power supply housing.
[0075] The inner diameter of the first channel 151 is larger than the radial dimension of the radial flange 31, so that the radial flange 31 and the first channel 151 can move relative to each other without obstruction. The radial dimension of the radial flange 31 is larger than the inner diameter of the second channel 151, so as to prevent one end of the connecting shaft 3 with the radial flange 31 from detaching from the first channel 151, and to ensure that the upper housing 1 and the lower housing 2 can maintain a stable connection during relative movement and during the flipping and opening process.
[0076] like Figure 8 As shown, a reset spring 4 is provided in the first channel 151. The length direction of the reset spring 4 is parallel to the length direction of the first channel 151. The reset spring 4 is fixed in the first channel 151 at one end close to the second body 232, and the connecting shaft 3 is located in the first channel 151 at the other end away from the second body 232.
[0077] Specifically, a return spring 4 is provided in the first channel 151. The radial dimension of the return spring 4 is smaller than the inner diameter of the first channel 151 and larger than the inner diameter of the second channel 151. When an external force is applied to the upper housing 1, the radial flange 31 moves toward the second end 131 of the second upper side plate 13 to unlock the locking part and the mating part 24. The return spring 4 is gradually compressed during the movement of the radial flange 31. When the locking part and the mating part 24 are unlocked, the external force is released. The elastic force of the compressed return spring 4 acts on the radial flange 31 and the side wall of the first channel 151. When released, it automatically and smoothly restores its deformation so that the radial flange 31 returns to its initial position. The radial flange 31 gradually moves toward the first end 121 of the first upper side plate 12 until the return spring 4 restores its deformation.
[0078] When the radial flange 31 moves to the first end 121 of the first channel 151 near the first upper side plate 12, the first body 222 is located between the first upper side plate 12 and the second upper side plate 13. When the upper shell 1 and the lower shell 2 are flipped open, the first body 222 will not affect the flipping of the upper shell 1, ensuring the smooth flipping process.
[0079] In another implementation, such as Figure 9 and Figure 10 As shown, a long strip-shaped connecting through hole 16 connecting the inner and outer sides is opened in the first upper side plate 12 and the second upper side plate 13 respectively. The length direction of the connecting through hole 16 is parallel to the horizontal plane. The connecting shaft 3 passes through the connecting through hole 16, and the end of the connecting shaft 3 located outside the upper housing 1 is provided with a radial flange 31. The diameter of the radial flange 31 in the vertical direction is greater than the width of the connecting through hole 16 in the vertical direction.
[0080] This embodiment utilizes connecting through holes 16 on both the inner and outer sides of the upper side plate. The connecting through hole 16 in the first upper side plate 12 penetrates through the first upper side plate 12, and the connecting through hole 16 in the second upper side plate 13 penetrates through the second upper side plate 13. This allows the end of the connecting shaft 3 away from the first connecting plate 221 to pass through the connecting through hole 16 and be positioned on the outside of the power supply housing. During transportation, this allows for the disassembly and separate packaging of the upper housing 1 and the lower housing 2, reducing transportation costs. Furthermore, when installing the power supply housing, the end of the connecting shaft 3 away from the radial flange 31 is inserted into the connecting channel from the outside of the upper side plate and fixed to the first connecting plate 221, enabling the simple and quick installation of the upper housing 1 and the lower housing 2.
[0081] The diameter of the radial flange 31 of the connecting shaft 3 located outside the upper housing 1 is greater than the width of the connecting through hole 16 in the vertical direction. The other end of the connecting shaft 3 is fixedly connected to the first connecting plate 221, so that the upper side plate is fixed between the first connecting plate 221 and the radial flange 31, ensuring the stability of the connection between the upper housing 1 and the lower housing 2, and improving the smoothness of the upper housing 1 and the lower housing 2 flipping open.
[0082] The radial flange 31 can be an enlarged structure integrally formed with the connecting shaft 3, or it can be a nut structure threadedly connected to the connecting shaft 3.
[0083] In another implementation of this embodiment, such as Figure 2 As shown, cylindrical shaft holes (not shown in the figure) that match the connecting shaft 3 are respectively opened on the first upper side plate 12 and the second upper side plate 13. The connecting shaft 3 passes through the shaft hole, and a radial flange 31 is provided at the end of the connecting shaft 3 located outside the upper housing 1. The diameter of the radial flange 31 is greater than the width of the shaft hole in the vertical direction.
[0084] The end of the connecting shaft 3 away from the radial flange 31 is provided with a first thread (not shown in the figure); the first connecting plate 221 is provided with a shaft hole through which the connecting shaft 3 passes, and the inner wall of the shaft hole is provided with a second thread. The second thread is tightened with the first thread to fix the connecting shaft 3 to the first end 121 of the first upper side plate 12 and the second upper side plate 13.
[0085] In one implementation of this embodiment, such as Figure 8 As shown, the snap-fit part is an elastic snap hook 14; a window 123 is provided at the third end 122 of the first upper side plate 12 and the fourth end 132 of the second upper side plate 13, and an elastic snap hook 14 is installed in each window 123. The elastic snap hook 14 includes: a fixed end 141, a snap-fit end 142 and a cantilever end 143. The fixed end 141 is fixedly connected to the first upper side plate 12 and the second upper side plate 13. The snap-fit end 142 is used to snap-fit with the mating part 24. The snap-fit end 142 protrudes out of the window 123 in the direction close to the second connecting plate 231. The cantilever end 143 is used to connect the fixed end 141 and the snap-fit end 142. When the snap-fit end 142 is subjected to force, the cantilever end 143 shifts away from the second connecting plate 23 in the direction within the window 123.
[0086] Second connecting plates 231 are symmetrically arranged on both sides of the second body 232. Each second connecting plate 231 is provided with a mating part 24 that respectively engages with the elastic hook 14 of an upper side plate to form a double-sided symmetrical locking, thereby fixing the closed state of the upper shell 1 and the lower shell 2 and improving the locking stability of the upper shell 1 and the lower shell 2.
[0087] like Figure 5 As shown, the mating part 24 is window-shaped to allow the locking end 142 to be inserted and locked. The locking end 142 protrudes from the window 123 in the direction near the second connecting plate 231, as shown in the figure. When the upper housing 1 and the lower housing 2 are closed, the locking end 142 can be inserted into the mating part 24 to improve the locking stability of the upper housing 1 and the lower housing 2.
[0088] The elastic hook 14 is disposed within the opening 123 of the upper side plate, and the fixed end 141 is fixedly connected to the upper side plate to support the snap-fit end 142 to shift from the inside to the outside of the upper side plate within the opening 123 during the process of contacting and pressing with the second connecting plate 231, thereby unlocking the snap-fit end 142 and the mating part 24. The cantilever end 143 connects the snap-fit end 142 and the fixed end 141, and the cantilever end 143 is elastic, so that when the snap-fit end 142 is pressed by the second connecting plate 231, the cantilever end 143 carries the snap-fit end 142 to shift outward from the power supply housing within the opening 123.
[0089] In another implementation, such as Figure 10As shown, the snap-fit part is a protrusion 17 located inside the third end 122 of the first upper side plate 12 and the fourth end 132 of the second upper side plate 13; the mating part 24 is a slot (not shown in the figure) or a through hole located in the second connecting plate 231. When the mating part 24 is a slot, the groove wall of the slot is an inclined guide surface.
[0090] The protrusion 17 can be formed on the upper side plate by stamping from the outside to the inside, as shown in the figure. The mating part 24 is a circular opening that mates with the protrusion 17, or a groove formed by stamping the second connecting plate 231 on the side near the upper side plate (not shown in the figure). In this embodiment, the protrusion 17 formed by stamping and the mating part 24 on the second connecting plate 231 are used to lock the upper housing 1 and the lower housing 2 into a closed state, thereby improving the stability of the locking of the upper housing 1 and the lower housing 2.
[0091] Furthermore, such as Figure 11 As shown, the length of the upper base plate 11 is greater than the length of the lower base plate 21. When the upper housing 1 and the lower housing 2 are closed, the end of the upper base plate 11 near the second lower side plate 23 extends away from the first lower side plate 22 and beyond the second lower side plate 23, forming an operating part 111 for receiving external force. When performing maintenance, the operator applies external force to the operating part 111 to unlock the mating part 24 and the snap-fit part, thereby flipping the upper housing 1 and opening the power supply housing. This embodiment achieves simple, convenient, and effortless opening of the power supply housing by setting the operating part 111.
[0092] This utility model provides a power supply housing, an access control power supply, and an access control system. The upper housing 1, consisting of an upper base plate 11, a first upper side plate 12, a second upper side plate 13, and a lower housing 2, consisting of a lower base plate 21, a first lower side plate 22, and a second lower side plate 23, forms a structure to house the access control power supply's PCB module, battery, and other components. The upper housing 1 and lower housing 2 are hinged at one end by a connecting shaft 3, allowing for rotational opening and closing of the other end. A snap-fit part and a mating part 24 are provided at the other end to ensure a fixed connection when the upper housing 1 and lower housing 2 are closed. This completely eliminates the need for traditional screw fastening. Users can easily unlock and flip the upper housing 1 to open the power supply housing. When closed, simply rotating and pressing the upper housing 1 engages the snap-fit part with the mating part 24 to lock the upper housing 1 and lower housing 2. This significantly simplifies the opening and closing operation of the power supply housing, requires no tools, and greatly improves maintenance efficiency. The upper housing 1 is connected to the lower housing 2 via the connecting shaft 3. During maintenance, the upper housing 1 can be flipped open to expose the PCB module, battery and other components mounted on the lower base plate 21 directly for maintenance. This avoids the problem of inconvenient maintenance due to insufficient space and further improves maintenance efficiency.

This power supply includes any of the power housings provided in Embodiment 1, and a PCB module and a battery installed within the power housing. In this embodiment, by using the power housing provided in Embodiment 1, the connecting shaft 3 provides a first end 121 of the first upper side plate 12 and a second end 131 of the second upper side plate 13 for stable rotation with the first lower side plate 22. The third end 122 of the first upper side plate 12 and the fourth end 132 of the second upper side plate 13 are both provided with locking portions for engaging with the mating portion 24 on the second lower side plate 23 for fixation. This prevents the upper housing 1 and lower housing 2 from opening due to external shaking or accidental contact, ensuring the protective performance of the power housing. Meanwhile, the input through hole 26 and the output through hole 27 are respectively set on the opposite first lower side plate 22 and second lower side plate 23, which avoids moving the wires during the opening of the power supply housing and ensures the stable connection of the wires. At the same time, the wires, input through hole 26, output through hole 27, PCB module and battery are all installed on the lower housing 2, which improves the functional integration of the lower housing 2 in the access control power supply.
