[0024] 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.

[0025] See also Figures 1 to 6 Now, a multi-voltage output power plug box provided by the utility model is described. The multi-voltage output power plug box comprises a housing 2, a power motherboard 10 and a plurality of plug-in voltage modules 1; the power motherboard 10 is arranged at the rear of the housing 2, and the plug-in voltage module 1 is fixed in the housing 2 and plugged with the power motherboard 10.

[0026] The utility model provides a power plug box with multi-voltage outputs. Compared with the prior art, each plug-in voltage module 1 serves as a separate power supply unit to supply power to other components of the toll collection robot. The plug-in voltage module 1 cooperates with the power motherboard 10 to supply power through a plug-in connection method, so that multiple power supplies can be used to supply power to different parts of the toll collection robot. The plug-in connection method facilitates the replacement and maintenance of the power supply units of different parts, and different power supply units can be replaced in a targeted manner, thereby improving maintenance efficiency.

[0027] The shell of the outer shell 2 is composed of a back plate, a front end plate, a top plate 15, a baffle plate 14, a bottom plate 12 and two side plates. The front end plate includes a plurality of sub-plates of equal width, and each sub-plate can be disassembled. After the sub-plates are removed, a working window is formed. The width of the sub-plate is consistent with the width of the plug-in voltage module 1. During installation, the sub-plates are removed to make way for the plug-in voltage module 1 to make way for the installation position. After the plug-in voltage module 1 is installed, the corresponding sub-plates that have been removed do not need to be installed again. The back plate of the outer shell 2 is arranged opposite to the front end plate. A clearance notch is left at the lower part of the back plate, and the clearance notch is used to install the AC high-voltage input port 9.

[0028] The power motherboard 10 is located at the rear side of several plug-in voltage modules 1 and is installed at the rear of the housing 2 to provide installation space for the plug-in voltage modules 1. The power motherboard 10 is close to the back plate of the housing 2 and there is a gap between the power motherboard 10 and the back plate. After the power motherboard 10 is installed, the power motherboard 10 is electrically connected to the AC high voltage input port 9, and the back plate is installed after the connection is completed. The back plate is fixed to the side plate of the housing 2 by screws.

[0029] The side panels on both sides of the housing 2 are connected with lining plates 4, and handles 5 are provided on the outside of the lining plates 4. The lining plates 4 are fitted to the side panels of the housing 2 and are installed on the side panels by means of screws. The front end of the lining plate 4 has a bent portion bent outward, the bent portion is parallel to the front end surface, and the bent portion extends toward the outside of the housing 2. A handle 5 is installed on the front side of the bent portion. The length direction of the handle 5 is consistent with the height direction of the housing 2.

[0030] Optionally, the plug-in voltage module 1 includes a mainboard 16, a panel, and a power supply unit module 11 disposed on the mainboard 16. When connected, the power supply unit module 11 is mounted on the mainboard 16 and plugged with the power motherboard 10 by means of the mainboard 16. When installed, the mainboard 16 is arranged longitudinally, the length direction of the mainboard 16 is consistent with the front-back direction of the housing 2, and the width direction of the mainboard 16 is consistent with the height direction of the housing 2. The panel of the plug-in voltage module 1 is provided with a voltage display unit 8 and a power switch 7, each of which realizes the individual switching of the power supply circuit of each component and the real-time display of the voltage.

[0031] The tail of the pluggable voltage module 1 is connected to the power motherboard 10 by means of a board-to-board connector. That is, the main board 16 of the pluggable voltage module 1 is connected to the power motherboard 10 by the board-to-board connector, so that current can pass. The pluggable voltage module 1 can be a DC power supply or an AC power supply.

[0032] In some possible embodiments, see Figure 3 and Figure 6 After being plugged into the power motherboard 10 , the plug-in voltage module 1 also needs to be limited by the housing 2 to maintain a stable state.

[0033] Inside the housing 2, a baffle plate 14 and a bottom plate 12 are longitudinally spaced apart. Opposite to the lower end face of the baffle plate 14 and the upper end face of the bottom plate 12, there are guiding card slots 13. The length direction of the guiding card slots 13 is consistent with the front-back direction of the housing 2. The upper and lower ends of the pluggable voltage module 1 are respectively limited within the guiding card slots 13.

[0034] The baffle plate 14 is located in the upper part of the housing 2. An installation space for installing the pluggable voltage module 1 is formed between the baffle plate 14 and the bottom plate 12. Both the lower end face of the baffle plate 14 and the upper end face of the bottom plate 12 are provided with guiding card slots 13. The guiding card slots 13 are grooves with a length direction along the front-back direction of the housing 2. During installation, the upper and lower ends of the main board 16 of the pluggable voltage module 1 are respectively connected and positioned within the upper and lower two guiding card slots 13.

[0035] Both the bottom plate 12 and the baffle plate 14 are of a perforated plate structure to improve the ventilation effect of the above-mentioned installation space. The ventilation holes opened on the baffle plate 14 and the bottom plate 12 can be uniformly distributed circular holes. The baffle plate 14 and the bottom plate 12 can be connected to the side plates of the housing 2 by means of screws. To improve the ventilation effect, there is a gap between the lower end face of the bottom plate 12 and the bottommost end of the housing 2. This gap ensures the ventilation effect of the bottom plate 12.

[0036] At the upper end of the housing 2, there is a top plate 15. Heat dissipation ventilation holes are opened on the top plate 15. A heat dissipation fan 3 is installed between the top plate 15 and the baffle plate 14. There is also a gap between the baffle plate 14 and the top plate 15. The heat dissipation fan 3 is installed within this gap. The blowing direction of the heat dissipation fan 3 is upward or downward, improving the air circulation effect within the inner cavity of the housing 2 to dissipate heat from the pluggable voltage module 1 and the power supply motherboard 10.

[0037] At the front end of the housing 2, there is a working window for the pluggable voltage module 1 to pass through. The panel of the pluggable voltage module 1 is limited within the working window. To further improve the installation stability of the pluggable voltage module 1, a clamping structure is provided at the upper and lower ends of the working window. The clamping structure includes a fixing plate and a plurality of buckles 6. The fixing plate is horizontally fixed on the housing 2. The plurality of buckles 6 are spaced on the fixing plate. The plurality of buckles 6 correspond to the plurality of pluggable voltage modules 1 one by one. Card slots for cooperating with the buckles 6 are opened on the panel of the pluggable voltage module 1.

[0038] When the pluggable voltage module 1 is not installed, the buckles 6 are used to clamp the daughter board. After the pluggable voltage module 1 is installed, the buckles 6 are used to clamp the panel of the pluggable voltage module 1. The upper and lower buckles 6 are oppositely arranged and are respectively used to clamp the symmetrically arranged card slots on the upper and lower parts of the panel.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
