[0002] A UPS is an uninterruptible power supply, which is a system device that connects a storage battery to a host and converts direct current into commercial power through module circuits such as a host inverter. It is mainly used to provide a stable output power supply for a single computer, a computer network system, or other power electronic devices such as solenoid valves and pressure transmitters.
[0003] The existing UPS power supply device is based on a lithium battery. Generally, the lithium battery is directly inserted into the device interior by a plug-in method. When the UPS power supply device is impacted, the internal battery module is prone to problems such as poor contact, which can easily affect the normal operation of the UPS power supply device. Summary of the Utility Model
[0004] In view of the deficiencies in the above-mentioned background art, the utility model provides a multifunctional lithium battery UPS power supply device.
[0005] The utility model adopts the following technical solutions:
[0006] A multifunctional lithium battery UPS power supply device, which comprises:
[0007] A box body, with an air outlet arranged at the top of the box body, an air inlet arranged at the bottom of the box body, a fixed mounting rack in the middle of the box body, a row of embedding grooves fixed at both the upper and lower ends of the mounting rack, and a second contact arranged on the inner surface of the box body, where the second contact is electrically connected to a power source or an electrical appliance;
[0008] A lithium battery, with a first contact and a fixed groove arranged on the back of the lithium battery, and a baffle arranged at the lower end of the notch of the fixed groove;
[0009] A positioning mechanism, which includes a hook, a torsion spring, and a first rotating rod. One end of the hook is provided with a tensioning part, and the two sides of the lower end of the tensioning part are respectively provided with a first inclined surface and a second inclined surface. The first rotating rod is fixed in the box body, and a corresponding hook is arranged for a group of upper and lower corresponding embedding grooves. A torsion spring is arranged on each hook, and the hook and the torsion spring are both sleeved outside the first rotating rod and rotate, so that the torsion spring presses down the tensioning part in the box body;
[0010] Among them, when the lithium battery is placed in the box body, the upper and lower ends of the lithium battery are respectively embedded into the upper and lower corresponding embedding grooves. When the tensioning part hooks the fixed groove on the back of the lithium battery, the second inclined surface presses against the baffle to tighten the lithium battery into the box body until the first contact and the second contact are tightly attached.
[0011] In a possible implementation, the positioning mechanism further includes a second rotating rod, a swinging member, and an adjusting member. The second rotating rod is fixed to the back surface inside the box body, and the second rotating rod is located on the first rotating rod. The swinging member is arranged on each of the hooks. The middle of the swinging member is sleeved on the second rotating rod. One end of the swinging member is flexibly connected to the upper end of the tensioning portion of the lower hook. The other ends of the swinging members are simultaneously fixed to the connecting rod. The adjusting member is screwed through the box body into the box body, and one end of the adjusting member inside the box body is fixed with a cone. The outer diameter of the cone gradually expands in a direction away from the connecting rod, and the lower end of the cone abuts against the connecting rod.
[0012] In a possible implementation, one end of the swinging member is connected to the upper end of the tensioning portion of the lower hook through a pulling rope.
[0013] In a possible implementation, the inner surface of the box body is a back plate. Connecting members are fixed on both sides of the back plate. The two ends of the second rotating rod are respectively fixed to the two connecting members. The second rotating rod is sleeved with limiting sleeves on both sides of each swinging member to limit the swinging member between the two limiting sleeves.
[0014] In a possible implementation, the mounting bracket includes a cross beam arranged vertically. The cross beam is fixed with a row of longitudinal beams. The embedding groove is arranged in the longitudinal beam, and a strip-shaped through hole is arranged on the top surface or the bottom surface of the longitudinal beam.
[0015] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages: When inserting the lithium battery into the box body along the embedding groove, the baffle of the lithium battery can be pushed against the first inclined surface of the tensioning portion of the hook to drive the hook to swing upward until the tensioning portion crosses the baffle and is embedded into the fixing groove. This way of inserting the lithium battery is relatively convenient and labor-saving. And during the process of the tensioning portion being embedded into the fixing groove, the second inclined surface gradually presses downward against the baffle under the action of the torsion spring to tighten the lithium battery into the box body, so that the first contact and the second contact are kept in a tightly attached state, which is beneficial to avoiding the phenomenon of poor contact.

[0028] In order to make the purpose, technical solutions and advantages of this application clearer, the following will further describe this application in detail with reference to the accompanying drawings.
[0029] Hereinafter, terms such as "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features.
[0030] In addition, in this application, orientation terms such as "upper" and "lower" are defined relative to the orientation in which the components in the drawings are schematically placed. It should be understood that these directional terms are relative concepts, which are used for relative description and clarification, and they can change accordingly with the change of the orientation in which the components in the drawings are placed.
[0031] What the present utility model discloses is a multifunctional lithium - battery UPS power supply device, as shown in the attached Figures 1 to 3As shown, the power supply device includes a box body 1, a lithium battery 2, and a positioning mechanism 3. Among them, an air outlet 101 is provided at the top of the box body 1, an air inlet 102 is provided at the bottom of the box body 1, and an exhaust fan 13 is fixed at the air outlet 101 inside the box body 1. An installation frame 12 is fixedly installed in the middle of the box body 1. A row of embedding grooves 103 are fixed at both the upper and lower ends of the installation frame 12. When the lithium battery 2 is placed in the box body 1, the upper and lower ends of the lithium battery 2 are respectively embedded into the two corresponding upper and lower embedding grooves 103, so that the lithium battery 2 is vertically placed in the box body 1 without collapsing, and a gap is formed between adjacent lithium batteries 2 to facilitate heat dissipation. When the exhaust fan 13 works, the hot air inside the box body 1 is pumped outwards, and the air outside the box body 1 enters the box body 1 due to the negative pressure formed as the air inside the box body 1 is pumped out, thereby forming a process of air circulation inside and outside the box body 1, thus improving the heat dissipation effect.
[0032] Continue to refer to the appendix Figure 2 , the installation frame 12 includes a cross beam 121 and a longitudinal beam 122. Transversely arranged cross beams 121 are fixed at both the upper and lower ends inside the installation frame 12, and a row of longitudinal beams 122 are fixed to both the upper cross beam 121 and the lower cross beam 121. The longitudinal beam 122 is a strip-shaped sheet metal part bent into a C shape, and the internal space formed after the longitudinal beam 122 is bent is the embedding groove 103, so as to form a structure in which a row of embedding grooves 103 are arranged in a one-to-one correspondence between the upper and lower cross beams 121. Further, a strip-shaped through hole (not shown in the appendix) is provided on the top surface or the bottom surface of the longitudinal beam 122, and the setting of this through hole facilitates the ventilation and heat dissipation of the lithium battery 2.
[0033] As shown in the appendix Figure 1 , 3 and 6, a box door 11 is also hinged at the open end of the box body 1. The side of the box door 11 away from the hinge can be fixed to the box door 11 by means of a buckle or a bolt, etc., and a cushion block 111 made of rubber is fixed on the surface of the box door 11 facing the inside of the box body 1. After the lithium battery 2 is inserted into the box body 1, the box door 11 is closed, and the cushion block 111 of the box door 11 can further push the lithium battery 2 into the box body 1 to fix it.
[0034] As shown in the appendix Figure 7 and 8 , a first contact 21 is provided on the back of the lithium battery 2, the inner surface of the box body 1 is a back plate 14, and a second contact 15 is also provided on the back plate 14. The second contact 15 is electrically connected to a power source or an electrical appliance. When the lithium battery 2 is inserted along the embedding groove 103, as shown in the appendix Figure 5 , the first contact 21 and the second contact 1 are in contact, so that the lithium battery 2 and the power source or the electrical appliance are electrically connected. Referring to the appendix Figure 4 again, a recessed fixing groove 201 is also provided on the back of the lithium battery 2, and a baffle 22 is provided at the lower end of the notch of the fixing groove 201. The fixing groove 201 and the baffle 22 are used to connect to the positioning mechanism 3 to fix the lithium battery 2.
[0035] As shown in the attached Figure 4 and 9 shown, the positioning mechanism 3 includes a hook 31, a torsion spring 32 and a first rotating rod 33. One end of the hook 31 is provided with a tension part 311, and a first inclined surface 312 and a second inclined surface 313 are respectively arranged on both sides of the lower end of the tension part 311. The first rotating rod 33 is fixed in the box body 1, and a set of corresponding upper and lower embedding grooves 103 are provided with a hook 31 respectively, and a torsion spring 32 is arranged on each hook 31. The hook 31 and the torsion spring 32 are both sleeved outside the first rotating rod 33 and rotate, and the straight end parts extending from both ends of the torsion spring 32 respectively abut against the back plate 14 and the hook 31, so that the torsion formed by the torsion spring 32 presses down the tension part 311 in the box body. When the lithium battery 2 is inserted along the embedding groove 103, the baffle 22 can be pushed towards the first inclined surface 312 to drive the hook 31 to swing upwards until the tension part 311 crosses the baffle 22 and is embedded into the fixing groove 201. During the process that the tension part 311 is embedded into the fixing groove 201, the second inclined surface 313 gradually presses down towards the baffle 22 under the action of the torsion spring 32, which can tighten the lithium battery 2 into the box body 1, so that the first contact 21 and the second contact 15 are kept in a tight state and avoid separation.
[0036] When it is necessary to take out the lithium battery 2 for replacement or maintenance, hold both sides of the lithium battery 2 with hands and pull outwards forcefully, so that the baffle 22 moves out of the box body 1 along the second inclined surface 313 to lift one end of the tension part 311 of the hook 31 upwards. After the baffle 22 passes through the tension part 311, the lithium battery 2 can be pulled out of the box body 1 easily without being restricted by the hook 31. Or as shown in the attached Figure 11 and 12 shown, the part of the hook 31 extending out of the box body 1 can be pressed downwards on the back of the box body 1, so that one end of the tension part 311 of the hook 31 is lifted upwards, and the lithium battery 2 can be pulled out of the box body 1 more easily. It can be seen that the utility model has multiple functions such as heat dissipation and being convenient for inserting and taking out the lithium battery 2.
[0037] Continue to refer to the attached Figure 4 and 9 , the positioning mechanism 3 further includes a second rotating rod 34, a swinging part 35, a connecting rod 36 and an adjusting part 38. The second rotating rod 34 is fixed on the back plate 14 in the box body 1, and the second rotating rod 34 is located above the first rotating rod 33. A swinging part 35 is arranged on each hook 31, and the middle of the swinging part 35 is sleeved on the second rotating rod 34. Its connection structure can be that connecting parts are fixed on both sides of the back plate 14, nuts are screwed on both ends of the second rotating rod 34, and both ends of the second rotating rod 34 respectively pass through the two connecting parts and then are screwed with nuts, so that the second rotating rod 34 can be fixed. Refer to the attached Figure 10, before the second rotating rod 34 is fixed, first put the swinging member 35 on the second rotating rod 34, and the second rotating rod 34 is sleeved with limiting sleeves 341 on both sides of each swinging member 35, so as to limit the swinging member 35 between the two limiting sleeves 341 to be only rotatable and not movable.
[0038] Continue to refer to the appendix Figure 9 , one end of each swinging member 35 is flexibly connected to the upper end of the tensioning part 311 of the lower hook 31 below it. The connection method is that one end of the swinging member 35 and the upper end of the tensioning part 311 of the lower hook 31 below it are connected by a pull rope 37. Specifically, hanging holes can be provided on both the swinging member 35 and the tensioning part 311, and both ends of the pull rope 37 pass through the hanging hole of the swinging member 35 and are tied to the hanging hole of the tensioning part 311 to achieve the connection. The other ends of each swinging member 35 are simultaneously fixed to the connecting rod 36, and by pushing the connecting rod 36, each swinging member 35 can be driven to swing simultaneously.
[0039] Refer to the appendix again Figure 4 and 9 , the adjusting member 38 spirally passes through the back plate 14 from the outside of the back of the box body 1 to the inside of the box body 1, and one end of the adjusting member 38 inside the box body 1 is fixed with a cone 381. The outer diameter of the cone 381 gradually expands in the direction away from the connecting rod 36, and the lower end of the cone 381 abuts on the connecting rod 36. During operation, by rotating the adjusting member 38 into the box body 1, the cone 381 moves from the back of the box body 1 to the inside of the box body 1. As the cone 381 moves, the connecting rod 36 can be pressed down, so as to drive one end of the swinging member 35 close to the tensioning part 311 to lift upward, and thus the tensioning part 311 can be lifted upward through the pull rope 37, so as to realize the simultaneous upward swing of each hook 31, which is convenient for overhauling or replacing all the lithium batteries 2 in the box body 1 at one time.
[0040] To sum up, when the lithium battery 2 is inserted into the box body 1 along the embedding groove 103, the baffle 22 of the lithium battery 2 can be pushed against the first inclined surface 312 of the tensioning part 311 of the hook 31 to drive the hook 31 to swing upward until the tensioning part 311 straddles the baffle 22 and is embedded into the fixing groove 201. This way of inserting the lithium battery 2 is more convenient and labor-saving. And during the process of the tensioning part 311 being embedded into the fixing groove 201, the second inclined surface 313 is gradually pressed downward against the baffle 22 under the action of the torsion spring 32, which can tighten the lithium battery 2 into the box body 1, so that the first contact 21 and the second contact 15 remain in a tightly attached state. In addition, after the lithium battery 2 is inserted into the box body 1, closing the box door 11 of the box body 1 can further push the first contact 21 of the lithium battery 2 against the second contact 15, thereby improving the firmness of the contact between the first contact 21 and the second contact 15, so that even if the box body 1 is impacted, the first contact 21 and the second contact 15 can always remain in a contact state, avoiding the phenomenon of poor contact.
[0041] The above is only the specific implementation manner of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantive modification made to the present utility model using this concept shall fall within the act of infringing the protection scope of the present utility model.
