However, this invention is not limited to the embodiments disclosed below, but can be implemented in various different forms. These embodiments are provided merely to complete the disclosure of this invention and to enable those skilled in the art to fully understand its scope, which is defined only by the scope of the claims. The same reference numerals denote the same constituent elements throughout the specification.

[0033] The present invention will now be described in detail with reference to the accompanying drawings.

[0034] like Figures 1 to 5 As shown, an IoT cabinet power supply device (hereinafter referred to as the power supply device) is provided for providing power to the IoT cabinet. An IoT server is installed in the IoT cabinet, and the power supply device is electrically connected to the IoT server to provide power to it. The IoT cabinet includes a cabinet body 8, with an openable cabinet door 81 on the cabinet body 8. The IoT server is installed inside the cabinet body 8. The power supply device and the cabinet body 8 are integrated into one structure, and the power supply device is installed on the top of the cabinet body 8.

[0035] The power supply device includes a housing 1, an interlocking mechanism, and a battery module. The housing 1 has a cuboid structure, with its length along the X direction (shown in the diagram), its width along the Y direction (shown in the diagram), and its height along the Z direction (shown in the diagram). The housing 1 includes a bottom plate 16, a top plate 17, a back plate 13, a partition plate 14, and two side plates 15. The bottom plate 16 is located at the bottom of the power supply device, the top plate 17 is located at the top of the power supply device, and the back plate 13 is located at one end of the housing 1 in the width direction. An opening 19 for inserting the battery module is formed at the end of the housing 1 opposite to the back plate 13. The two side plates 15 are located at opposite ends of the housing 1 in the length direction. A cavity for installing the battery module is formed inside the housing 1. The partition plate 14 is disposed within the cavity of the housing 1, dividing the cavity into two receiving chambers. The two receiving chambers are spaced apart along the length direction of the housing 1 and are designated as a first receiving chamber 11 and a second receiving chamber 12. The partition plate 14 is perpendicularly connected to the back plate 13. Each receiving cavity contains one battery module, meaning there are two battery modules: a first battery module 5 and a second battery module 6. When installing the battery modules, they are inserted into the corresponding receiving cavity through opening 19, with the insertion direction being the Y direction as shown in the diagram. Each receiving cavity has two connection terminals 4 on its inner wall. When the battery module is inserted, its positive and negative terminals are electrically connected to the two connection terminals 4, respectively, thus completing the circuit.

[0036] The interlocking mechanism serves to interlock the two battery modules. There are two interlocking mechanisms, one for locking the other two battery modules. The two interlocking mechanisms are designated as first interlocking mechanism 2 and second interlocking mechanism 3. First interlocking mechanism 2 and second interlocking mechanism 3 have identical structures and are spaced apart along the width of housing 1. First interlocking mechanism 2 locks the first battery module 5, and second interlocking mechanism 3 locks the second battery module 6. The interlocking mechanism includes a locking pin and a locking rod. The locking pin is elastically mounted on housing 1, with one end extending into one of the receiving cavities and inserting into the corresponding battery module. The locking rod is elastically mounted on housing 1, with one end extending into another receiving cavity, and the second end selectively abutting against the locking pin and restricting its movement.

[0037] Specifically, the locking and unlocking of the battery module is achieved through the coordinated movement of the locking pin and the locking lever. The locking pin is elastically connected to the partition 14 in the housing 1, and can move elastically along its own length. In the free state, one end of the locking pin extends into the receiving cavity and is inserted into the corresponding battery module. When the locking lever separates from the locking pin, the locking lever cannot restrict the elastic movement of the locking pin, and the battery module can be pulled out, i.e., the interlocking mechanism is in the unlocked state; when the locking lever abuts against the locking pin, the locking lever rests against one end of the locking pin in the direction of movement, and the locking lever can restrict the elastic movement of the locking pin. At this time, the locking pin cannot separate from the battery module, and therefore the battery module cannot be pulled out from the receiving cavity, i.e., the interlocking mechanism is in the locked state.

[0038] Reference Figure 6 As shown, the battery module has a cuboid structure, and its shape and size match the corresponding receiving cavity. Along the insertion direction of the battery module, the end facing the back plate 13 is the front face 63, and the positive and negative terminals of the battery module are located on the front face 63. Along the length of the housing 1, the two opposite ends of the battery module are side faces 64. One side face 64 of the battery module has a locking hole 61 for insertion with a corresponding locking pin. The side face 64 of the battery module has a clearance notch 62 for clearance of the locking pin. The clearance notch 62 is located between the front face 63 and the locking hole 61, and one end of the clearance notch 62 penetrates through the front face 63. The sidewall of the clearance notch 62 facing away from the front face 63 is adjacent to the locking hole 61, and this sidewall is sloped. The locking pin can slide along the slope, and simultaneously utilizes the slope to push the locking pin elastically.

[0039] Specifically, refer to Figure 2 and Figure 3 As shown, the first interlocking mechanism 2 includes a first locking pin 21, a first locking rod 22, a first spring 23, and a second spring 24. The first locking pin 21 is a round rod structure, and one end of the first locking pin 21 is used to insert into the locking hole 61 on the first battery module 5. Both the end of the first locking pin 21 that is inserted into the locking hole 61 and the locking hole 61 are spherical structures, and the two are fitted together. The first locking rod 22 is a "C" shaped structure, and the first locking rod 22 includes a first rod segment 221, a second rod segment 222, and a third rod segment 223. The first rod segment 221 and the third rod segment 223 are respectively disposed at both ends of the second rod segment 222, and the first rod segment 221 is perpendicular to the second rod segment 222, and the third rod segment 223 is perpendicular to the second rod segment 222. The ends of the first rod segment 221 and the third rod segment 223 that are away from the second rod segment 222 extend in the same direction.

[0041] A first locking pin 21 is installed in a first guide hole 141, and a first spring 23 is sleeved on the first locking pin 21. One end of the first spring 23 is fixed to the first locking pin 21, and the other end is fixed to the wall of the first guide hole 141. When the first spring 23 is in a free state, one end of the first locking pin 21 is located in the first receiving cavity 11. A second rod segment 222 is installed in a first cavity 131, and the second rod segment 222 is elastically connected to the inner wall of the first cavity 131 through a second spring 24, so that the second rod segment 222 can move elastically, and the direction of movement of the second rod segment 222 is the Y direction shown in the figure. The first rod segment 221 is located in a first connecting hole 133, and one end of the first rod segment 221 can extend into the second receiving cavity 12. A third rod segment 223 is located in a second connecting hole 134, and one end of the third rod segment 223 can extend into the first guide hole 141. When the second spring 24 is in its free state, the end of the first rod segment 221 that is away from the second rod segment 222 (i.e., the first end of the first locking rod 22) is located in the second receiving cavity 12, and the end of the third rod segment 223 that is away from the second rod segment 222 (i.e., the second end of the first locking rod 22) is located in the first guide hole 141. The third rod segment 223 abuts against the end of the first locking pin 21 that is away from the first receiving cavity 11, so that the first locking pin 21 cannot move in the direction away from the first receiving cavity 11.

[0042] Specifically, refer to Figure 4 and Figure 5As shown, the second interlocking mechanism 3 includes a second locking pin 31, a second locking rod 32, a first spring 23, and a second spring 24. The second locking pin 31 is a round rod structure, and one end of the second locking pin 31 is used to insert into the locking hole 61 on the second battery module 6. Both the end of the second locking pin 31 that is inserted into the locking hole 61 and the locking hole 61 are spherical structures, and the two are fitted together. The second locking rod 32 is a "C" shaped structure, and the second locking rod 32 includes a first rod segment 221, a second rod segment 222, and a third rod segment 223. The first rod segment 221 and the third rod segment 223 are respectively disposed at both ends of the second rod segment 222, and the first rod segment 221 is perpendicular to the second rod segment 222, and the third rod segment 223 is perpendicular to the second rod segment 222. The ends of the first rod segment 221 and the third rod segment 223 that are away from the second rod segment 222 extend in the same direction.

[0043] A second guide hole 142 is provided on the partition 14, one end of which communicates with the second receiving cavity 12. The length direction of the second guide hole 142 is the X direction shown in the figure. A second cavity 132 is provided on the back plate 13, one end of which communicates with the first receiving cavity 11 through a third connecting hole 135. The other end of the second cavity 132 communicates with the second guide hole 142 through a fourth connecting hole 136. The third connecting hole 135 and the fourth connecting hole 136 are perpendicular to the second guide hole 142.

[0044] The second locking pin 31 is installed in the second guide hole 142, and the first spring 23 is sleeved on the second locking pin 31. One end of the first spring 23 is fixed to the second locking pin 31, and the other end is fixed to the wall of the second guide hole 142. When the first spring 23 is in the free state, one end of the second locking pin 31 is located in the second receiving cavity 12. The second rod segment 222 is installed in the second cavity 132, and the second rod segment 222 is elastically connected to the inner wall of the second cavity 132 through the second spring 24, so that the second rod segment 222 can move elastically, and the direction of movement of the second rod segment 222 is the Y direction shown in the figure.

The third rod segment 223 abuts against the end of the second locking pin 31 that is away from the second receiving cavity 12, so that the second locking pin 31 cannot move in the direction away from the second receiving cavity 12.

[0045] Specifically, refer to Figure 1 and Figure 7As shown, heat dissipation channels 18 are provided within the partition 14 and the back plate 13. The two ends of the heat dissipation channels 18 extend through both ends of the housing 1 along its length. A cooling fan 7 is provided at one end of the housing 1 along its length, driving air to flow along the heat dissipation channels 18. By providing the heat dissipation channels 18, the battery module can be cooled, improving the overall heat dissipation performance of the power supply device.

[0046] Specifically, refer to Figure 1 As shown, a guide groove 151 is provided on the cavity wall of the receiving cavity. Specifically, guide grooves 151 are provided on both the partition 14 and the side plate 15. Correspondingly, a guide rail is provided on the side 64 of the battery module. The guide rail is configured to cooperate with the guide groove 151 so that the battery module and the cavity wall of the receiving cavity are slidably connected through the guide groove 151 and the guide rail, thereby facilitating the installation of the battery module.

[0047] In this embodiment, the specific working principle of the power supply device is as follows: when the first battery module 5 and the second battery module 6 are respectively inserted into the first receiving cavity 11 and the second receiving cavity 12, the first locking pin 21 in the first interlocking mechanism 2 is inserted into the locking hole 61 on the first battery module 5. At the same time, the front end face 63 of the second battery module 6 abuts against the first rod segment 221 in the first locking rod 22 and pushes the entire first locking rod 22 to move toward the back plate 13. At this time, the second spring 24 is compressed, and the third rod segment 223 in the first locking rod 22 separates from the first locking pin 21. The entire first interlocking mechanism 2 is in the unlocked state, and the first locking pin 21 can move elastically in the X direction shown in the figure. Similarly, the second locking pin 31 in the second interlocking mechanism 3 is inserted into the locking hole 61 on the second battery module 6. At the same time, the front end face 63 of the first battery module 5 abuts against the first rod segment 221 of the second locking rod 32, pushing the entire second locking rod 32 towards the back plate 13. At this time, the second spring 24 is compressed, and the third rod segment 223 of the second locking rod 32 separates from the second locking pin 31. The entire second interlocking mechanism 3 is in the unlocked state, and the second locking pin 31 can move elastically in the X direction shown in the figure.

[0048] When the first battery module 5 needs to be removed for charging, it can be directly pulled out because the first interlocking mechanism 2 is in the unlocked state. As the first battery module 5 is pulled out, the inclined surface on the clearance notch 62 pushes the first locking pin 21 towards the second receiving cavity 12. After the first battery module 5 is removed, the pressure on the second locking rod 32 in the second interlocking mechanism 3 is released, and the second spring 24 drives the second locking rod 32 towards the opening 19 of the receiving cavity. At this time, the third segment 223 of the second locking rod 32 moves to the end of the second locking pin 31 away from the second receiving cavity 12. Under the action of the second locking rod 32, the second locking rod 32 restricts the movement of the second locking pin 31, preventing it from moving away from the second receiving cavity 12; that is, the second interlocking mechanism 3 is in the locked state. Because the second interlocking mechanism 3 is locked, the second locking pin 31 cannot move, therefore the second battery module 6 cannot be removed. Similarly, when the second battery module 6 is pulled out first, the first interlocking mechanism 2 is locked, preventing the first battery module 5 from being pulled out. It can be understood that by setting the first interlocking mechanism 2 and the second interlocking mechanism 3, once one battery module is pulled out of its corresponding receiving cavity, the other battery module cannot be pulled out. This prevents the operator from accidentally pulling out both battery modules, thus avoiding a power outage to the entire IoT cabinet.

[0049] In this embodiment, two receiving cavities are provided within the housing 1, each housing cavity housing one battery module. Two interlocking mechanisms are provided on the housing 1, each locking one battery module. The interlocking structure includes a locking pin and a locking rod that are interconnected; locking and unlocking are achieved by the contact or separation between the locking pin and the locking rod. Simultaneously, the locking pin is inserted into one battery module, and the locking rod abuts against the other battery module. This structure associates the two battery modules; when one battery module is removed, the interlocking mechanism locks the other battery module, preventing both battery modules from being pulled out and causing an accidental power outage.

[0050] Although embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above embodiments, but can be made in various forms, and those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential characteristics of the present invention. Therefore, it should be understood that the above embodiments are exemplary in all respects and not restrictive.
