These advantages meet the flexible, automated, and efficient logistics requirements of modern hospitals.

[0003] As an important component and power source of logistics robots, the battery's size, capacity, weight, etc. must be considered first at the beginning of product design. This not only affects the industrial design of the logistics robot, but also directly affects its investment cost, operating efficiency, applicability, reliability and safety.

[0004] CN213242709U discloses a lithium battery pack for a logistics robot, comprising an outer battery box, an inner battery box, and a protective cover plate on the top of the inner battery box. A number of evenly distributed protective rubber pads are adhered to the outer walls of both sides of the outer battery box by glue. A number of evenly distributed heat dissipation grooves are provided on the two side panels of the outer battery box perpendicular to the protective rubber pads. A mounting and fixing mechanism is fixedly connected to the top of the outer walls of both sides of the outer battery box. A battery inner box is provided inside the outer battery box. Both sides of the upper surface of the inner battery box are movably connected to the protective cover plate by hinges. Heat dissipation grooves and strip heat dissipation grooves are provided on the outer battery box and the inner battery box, respectively.

[0005] With the popularization and applicability of logistics robots, in order to extend the battery life of logistics robots, the power supply of logistics robots is a more critical issue. The power supply equipment in existing logistics robots usually uses multiple lithium batteries for installation and fixation. During the operation of the logistics robots, the current installation of the battery pack is prone to shaking, which easily causes the battery packs to collide with each other, posing installation risks and affecting the service life. In addition, the current power supply equipment is not stable enough when charging. Utility Model Content

[0037] With the popularization and applicability of logistics robots, in order to extend the battery life of logistics robots, the power supply of logistics robots is a more critical issue. The power supply equipment in existing logistics robots usually uses multiple lithium batteries for installation and fixation. During the operation of the logistics robots, the current installation of the battery pack is prone to shaking, which easily causes the battery packs to collide with each other, posing installation risks and affecting the service life. In addition, the current power supply equipment is not stable enough when charging.

[0038] The utility model provides a power supply device, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in this embodiment, the power supply device includes a shell, a battery assembly and a power protection plate 5; the shell includes a mounting base plate 1, a mounting side plate 2, a mounting cover plate 3 and an internal fixing plate 4, wherein the mounting side plate 2 is arranged on the side of the mounting base plate 1, and the mounting base plate 1, the mounting side plate 2 and the mounting cover plate 3 cooperate to form a closed mounting cavity, and the battery assembly and the power protection plate 5 are arranged in the mounting cavity to form a sealed space to isolate external factors and ensure the stability of the battery assembly.

In order to further prevent the impact of external impact on the battery assembly, a shock-absorbing layer is provided on the inner side of the mounting cover plate 3, the mounting side plate 2 and the mounting base plate 1, and the shock-absorbing layer can be provided with a buffer cotton.

[0039] Specifically, the upper and lower ends of the battery assembly are respectively abutted and fixed to the mounting cover 3 and the mounting base 1, and the battery assembly is protected and fixed from the upper and lower ends of the battery assembly by the mounting cover 3 and the mounting base 1. The power protection plate 5 is fixed to the mounting base 1 by screws and is located on one side of the battery assembly; one end of the side of the battery assembly abuts against the mounting side plate 2, and the other end is provided with an internal fixing plate 4, and the battery assembly is abutted and fixed from both sides of the battery assembly by the internal fixing plate 4 and the mounting side plate 2; one end of the internal fixing plate 4 abuts against the battery assembly, and the other end abuts against the mounting side plate 2.

[0040] By installing the base plate 1, the side plate 2, the cover plate 3 and the internal fixing plate 4, when the battery assembly is installed, the battery assembly is fixed from the upper and lower ends of the battery assembly by the cooperation of the cover plate 3 and the base plate 1, and the battery assembly is fixed from both sides of the battery assembly by the cooperation of the side plate 2 and the internal fixing plate 4. In addition, different sizes of internal fixing plates 4 can be replaced to adapt to different sizes of battery assemblies for fixation.

[0042] In order to adapt to battery assemblies of different sizes, the internal fixing plate 4 is set to a replaceable structure, so that battery assemblies of different sizes can be fixed by replacing internal fixing plates 4 of different sizes, thereby improving the overall adaptability; in other embodiments, in order to avoid frequent replacement of the internal fixing plate 4, the internal fixing plate 4 can be set to a retractable structure.

[0043] In order to ensure the stability of the battery cells 9 inside the battery assembly, that is, the battery pack, and avoid the battery cells 9 shaking and colliding with each other during operation; the battery assembly is provided with a side fixing plate 7, an adapter plate 8 and at least two electrically connected battery cells 9, and the number of battery cells 9 is adjusted according to actual conditions; wherein, there are two side fixing plates 7, the two side fixing plates 7 are symmetrically arranged on both sides of the battery cell 9, and the two ends of the adapter plate 8 are connected to the two side fixing plates 7; the battery cell 9 is connected to the adapter plate 8, and the multiple battery cells 9 are electrically connected through the adapter plate 8; the battery cell 9 is fixed and protected by the side fixing plates 7 on both sides to avoid direct external impact on the battery pack, thereby improving safety.

Only an integral slot body needs to be opened on the logistics robot, and there is no need to open a complicated slot body to match the shell. The installation is convenient and the stability is high.

[0048] In order to carry out integrated control of the battery assembly and control the current input and output of the battery assembly, a control circuit is provided on the power protection board 5, and a connecting line is provided on one side of the power protection board 5, and the connecting line includes a first connecting line 12 and a second connecting line 13; the first connecting line 12 connects the battery assembly and the power protection board 5, one end of the second connecting line 13 is connected to the power protection board 5, and the other end passes through the outside of the shell and is connected to the logistics robot; a through hole for the second connecting line 13 to pass through is opened on the mounting side panel 2, and a rubber ring 14 is provided in the through hole, and the through hole is sealed by the rubber ring 14 to isolate the air inside and outside.
