The upper end of the sinking rod 402 is connected to a carrier rod 401, and the upper end of the carrier rod 401 is fixedly connected to a carrier plate 400.

[0039] An installation assembly is provided on one side surface of the carrier plate 400. Two converging assemblies are respectively provided on the other two side surfaces of the carrier plate 400. A trigger assembly is provided on one of the converging assemblies, and a locking assembly is provided on the other converging assembly. When the lithium battery pack is placed on the carrier plate 400, the carrier plate 400 sinks under the gravity of the lithium battery pack to drive the installation assembly to fix the lower part of the lithium battery pack, and synchronously drive the two converging assemblies to converge, so as to trigger the docking and locking of the trigger assembly and the locking assembly, and further drive one end of the locking assembly to extend into the housing 100.

[0040] In the present invention, a carrier plate 400 that can descend inside the housing 100 is provided to carry the lithium battery pack. When the lithium battery pack is placed on the carrier plate 400, the gravity of the lithium battery pack drives the carrier plate 400 to sink, so as to drive the installation assembly to fix the lower part of the lithium battery pack, and synchronously drive the two beam components to beam, so as to trigger the docking and locking of the trigger component and the locking component, fix the lithium battery pack on the carrier plate 400, and further drive one end of the locking component to extend into the housing 100, so that the lithium battery pack is also fixed to the housing 100, ensuring that the lithium battery pack always maintains stable fixation during transportation or operation.

[0041] In an embodiment further provided by the present invention, a bearing spring 403 is connected between the bearing rod 401 and the sinking hole, and the bearing spring 403 is arranged on the surface of the sinking rod 402.

[0042] Specifically, when the lithium battery pack is placed on the carrier plate 400, the carrier plate 400 sinks to compress the bearing spring 403. The bearing spring 403 is used to reset the carrier plate 400 after the lithium battery pack is taken out, and at the same time provide a certain damping effect when carrying the lithium battery pack.

[0043] In an embodiment further provided by the present invention, the installation assembly includes a connecting piece 500 connected to one side surface of the carrier plate 400, and one end of the connecting piece 500 is rotatably connected to a connecting shaft 501.

Two limiting sliding grooves 503 are provided at both ends of the fixing clip 502, and both ends of the connecting shaft 501 are respectively slidably connected to the two limiting sliding grooves 503.

[0044] Furthermore, the outwardly extending part at the upper end of the fixing clip 502 is used as a claw part for fixing.

[0045] Specifically, when the carrier plate 400 descends, it drives the connecting shaft 501 to slide in the limiting sliding groove 503, so that the fixing clip 502 rotates inward with the first rotating shaft 504 as the axis, so that the claw part of the fixing clip 502 presses against the lower edge of the lithium battery pack to fix the lithium battery pack.

[0046] In an embodiment further provided by the present invention, the beam component includes a transmission member 600 connected to the other side surface of the carrier plate 400, and one end of the transmission member 600 is rotatably connected to a transmission shaft 601. The other side surface inside the housing 100 is rotatably connected to a second rotating shaft 604, and one end of the second rotating shaft 604 is connected to a beam strip 602. Two beam sliding grooves 603 are provided at both ends of the beam strip 602, and both ends of the transmission shaft 601 are respectively slidably connected to the two beam sliding grooves 603.

[0047] Specifically, when the carrier plate 400 descends, it drives the transmission shaft 601 to slide in the converging chute 603, causing the converging strip 602 to rotate inward around the second rotating shaft 604, so that the converging strip 602 abuts against the two side surfaces of the lithium battery pack.

[0048] In an embodiment further provided by the present invention, the triggering assembly includes a first converging rod 700 connected to one side surface of one of the converging strips 602. One end of the first converging rod 700 is provided with a first triggering hole and a second triggering hole. The first converging rod 700 is also provided with an unlocking groove 701. A triggering rod 703 is slidably connected in the first triggering hole. A locking member 707 is slidably connected in the second triggering hole. The inner end of the triggering rod 703 is connected with a first connecting strip 704. One end of the first connecting strip 704 is rotatably connected with a second connecting strip 705. The middle of the second connecting strip 705 is rotatably connected to both side surfaces of the unlocking groove 701 through a rotating shaft. One end of the second connecting strip 705 is rotatably connected with a third connecting strip 706. One end of the third connecting strip 706 is connected to the inner end of the locking member 707. An unlocking block 702 is slidably connected in the unlocking groove 701. The lower end of the unlocking block 702 is connected to the surface of the locking member 707.

[0049] In an embodiment further provided by the present invention, the locking assembly includes a second converging rod 800 connected to one side surface of the other converging strip 602. The second converging rod 800 is internally provided with a first locking hole and a second locking hole. A limiting groove is provided on the surface of the second locking hole. A touch rod 801 is slidably connected in the second locking hole. A sliding block 803 is connected to the surface of the touch rod 801. The sliding block 803 is slidably connected with the limiting groove. A first touch groove 802 is provided in the middle of the touch rod 801. A connecting strip 804 is connected in the first touch groove 802. A locking tube 805 is slidably connected in the first locking hole. One end of the locking tube 805 is also rotationally matched with one end inside the first locking hole. The locking tube 805 is provided with a locking groove 807 and a second touch groove 808. One end of the locking tube 805 is connected with a locking block 806. One end of the connecting strip 804 is rotatably connected with the second touch groove 808. A limiting member 809 is provided on the surface of the second converging rod 800. One end of the limiting member 809 penetrates the surface of the second converging rod 800 and is slidably connected with the locking groove 807.

[0050] Furthermore, the locking groove 807 is of a "<" - shaped groove structure. Due to the fixed setting of the limiting member 809 and the rotational connection between the connecting strip 804 and the first touch groove 802, the movement track of the locking tube 805 under the action of the locking groove 807 is a horizontal movement followed by a rotational movement.

[0051] In a further embodiment provided by the present invention, a mating hole is further provided inside the second converging rod 800. The locking member 707 is adapted to the position of the mating hole. One end of the actuating rod 801 penetrates through the converging strip 602 and is connected with a fixing rod 810. A disassembly hole is provided on one side of the housing 100. One end of the fixing rod 810 is adapted to the position of the disassembly hole.

[0052] Furthermore, the end of the locking member 707 is wider than the middle part to form a groove structure for mating locking.

[0053] Specifically, when the converging strip 602 rotates inwardly, the first converging rod 700 and the second converging rod 800 are driven to move inwardly, so that the inner ends of the first converging rod 700 and the second converging rod 800 gradually approach each other. The trigger rod 703 first contacts the second converging rod 800, and slides inwardly in the first trigger hole under pressure, thereby driving the second connecting strip 705 to rotate, so as to drive the locking member 707 to slide outwardly in the second trigger hole, so that the locking member 707 enters the mating hole, and thus abuts against one end of the actuating rod 801, causing the actuating rod 801 to slide inwardly in the second locking hole, so as to drive the locking tube 805 to slide inwardly and rotate together, so as to generate rotation when about to contact the end of the locking member 707, causing the locking block 806 to rotate out and abut against the locking member 707 to lock and fix the locking member 707.

[0054] Furthermore, when the actuating rod 801 slides inwardly, it will also drive the fixing rod 810 to slide together, so that one end of the fixing rod 810 slides into the disassembly hole, so that the lithium battery pack and the housing 100 are also locked and fastened together, further strengthening the fixation of the lithium battery pack.

[0055] Furthermore, when disassembling the lithium battery pack, while pushing the fixing rod 810 out of the disassembly hole, pull the unlocking block 702 to disengage the locking member 707 from the mating hole, and then lift and take out the lithium battery pack to complete the disassembly.

[0056] In a further embodiment provided by the present invention, it further includes a cover body 104. A handle 105 is fixedly connected to one side surface of the cover body 104. Two storage grooves 106 are provided on both side surfaces of the cover body 104. Two storage strips 101 are connected to both side surfaces inside the housing 100. The two storage strips 101 are respectively in sliding fit with the two storage grooves 106. A closing groove 102 is provided on one side surface of the housing 100. A locking groove 103 is provided on the other side of the housing 100. The closing groove 102 is communicated with the locking groove 103.

[0057] In an embodiment further provided by the present invention, a closing block 200 is connected to the inner surface of one side of the cover body 104, a mating groove 201 is provided at one end of the closing block 200, a locking block 202 is rotatably connected in the mating groove 201, a locking spring 203 is connected between the inner surface of one side of the mating groove 201 and the one side surface of the locking block 202, the closing block 200 is slidably matched with the closing groove 102, and the locking block 202 is adapted to the position of the locking groove 103.

[0058] Specifically, after the lithium battery pack is installed, the storage slot 106 of the cover body 104 is aligned with the storage strip 101 and pushed in, so that the closing block 200 enters the closing slot 102, and the outer end of the locking block 202 abuts against the inner wall of the closing slot 102 and rotates and is received into the matching slot 201. When it reaches the locking slot 103, the locking spring 203 resets and pops out the locking block 202, so that the locking block 202 is engaged with the locking slot 103, so that the cover body 104 is fixed to the shell 100.

[0059] Furthermore, when removing the cover 104 , it is only necessary to pry the locking block 202 so that the locking block 202 rotates to be parallel to the inner wall of the locking groove 103 , and then pull out the cover 104 to complete the removal.

[0060] In an embodiment further provided by the present invention, an assembly bracket 301 is carried on the upper surface of the carrier plate 400, a battery body 300 is installed in the assembly bracket 301, a plurality of nickel strips 302 are provided at both ends of the battery body 300, and a protective plate 303 is provided on one side surface of the assembly bracket 301.

[0061] Furthermore, each row of battery bodies 300 forms a group, and the battery bodies 300 of adjacent groups are placed in opposite directions, that is, the positive poles of the battery bodies 300 of the previous row are on top and the negative poles are on the bottom, while the negative poles of the battery bodies 300 of the next row are on top and the positive poles are on the bottom.

[0062] Furthermore, the nickel strips 302 are spot-welded to the poles of adjacent battery bodies 300 , so that the positive and negative poles of the adjacent battery bodies 300 are connected in parallel and in series.

[0063] Specifically, the battery body 300 , the assembly bracket 301 , the nickel strip 302 and the protection plate 303 are assembled together to form the high-performance lithium battery pack of the present invention.

[0064] In the present invention, first, the battery body 300 is installed into the assembly bracket 301. Subsequently, the nickel strip 302 is welded to the pole part of the battery body 300. Then, the wire harness on the protection board 303 is connected to the nickel strip 302 to form a lithium battery pack. Subsequently, the lithium battery pack is placed on the carrier plate 400. Under the gravity of the lithium battery pack, the carrier plate 400 sinks, thereby driving the connecting shaft 501 to slide in the limit chute 503, causing the fixing clip 502 to rotate inward with the first rotating shaft 504 as the axis, so that the claw part of the fixing clip 502 presses against the upper edge of the lower assembly bracket 301, thereby preliminarily fixing the lithium battery pack. Synchronously, when the carrier plate 400 sinks, it will also drive the transmission shaft 601 to slide in the converging chute 603, causing the converging strip 602 to rotate inward with the second rotating shaft 604 as the axis, so that the converging strip 602 abuts against the two side surfaces of the lithium battery pack. When the converging strip 602 rotates inward, the first converging rod 700 and the second converging rod 800 are driven to move inward, so that the inner ends of the first converging rod 700 and the second converging rod 800 gradually approach. The trigger rod 703 first contacts the second converging rod 800 and slides inward in the first trigger hole under pressure, thereby driving the second connecting strip 705 to rotate, so as to drive the locking part 707 to slide outward in the second trigger hole, making the locking part 707 enter the mating hole, thereby abutting against one end of the trigger rod 801, causing the trigger rod 801 to slide inward in the second locking hole, so as to drive the locking tube 805 to slide inward and rotate together, so that when it is about to contact the end of the locking part 707, it rotates, causing the locking block 806 to rotate out and abut against the locking part 707, locking and fixing the locking part 707, so that the first converging rod 700 and the second converging rod 800 are connected and fastened to the upper surface of the upper assembly bracket 301, completing the fixation of the lithium battery pack. Synchronously, when the trigger rod 801 slides inward, it will also drive the fixing rod 810 to slide together, so that one end of the fixing rod 810 slides into the disassembly hole, so that the lithium battery pack and the housing 100 are also locked and fastened, further strengthening the fixation of the lithium battery pack, thus conveniently completing the installation of the lithium battery pack and making the installation of the lithium battery pack very stable. Finally, the receiving groove 106 of the cover body 104 is aligned with the receiving strip 101 and pushed in, so that the closing block 200 enters the closing groove 102. The outer end of the locking block 202 abuts against the inner wall of the closing groove 102 and rotates, and is received into the mating groove 201. When it reaches the locking groove 103, the locking spring 203 resets and pops out the locking block 202, so that the locking block 202 is engaged into the locking groove 103, fixing the cover body 104 to the housing 100 and completing all installations.

[0065] Only some exemplary embodiments of the present invention have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
