Lithium batteries have high energy, long service life, and high rated voltage, and are widely used in real life, often used to provide power for electric vehicles.

[0003] However, in traditional lithium batteries, the batteries are mainly fixed to the battery slots in electric vehicles by bolts. In order to save space, the outer wall of the lithium battery is usually tightly fitted to the inner wall of the battery slot. When the lithium battery needs to be replaced, the heavy weight of the lithium battery and the depth of the battery slot make it inconvenient for the operator to remove the lithium battery from the battery slot.

[0004] Therefore, it is necessary to provide a new, easy-to-install lithium battery to solve the above-mentioned technical problems. Summary of the Invention

[0008] Preferably, a set of positioning grooves are equidistantly provided on the lower circumferential part of the outer surface of the annular block, and a positioning rod is slidably installed on the upper rear side of the inner cavity of the sealing shell, and the positioning rod is movably connected to the positioning groove.

[0009] Preferably, a first compression spring is movably sleeved on the outer surface of the positioning rod, and the two ends of the first compression spring are fixedly connected to the outer surface of the positioning rod and the inner wall of the sealing shell, respectively.

[0012] Compared with related technologies, the lithium battery provided by this invention, which is easy to install, has the following advantages:

[0013] This invention provides an easy-to-install lithium battery. By flipping open the sealed casing, a push-pull rod moves upward, causing a connecting block to move, which in turn moves the connecting plate vertically, and consequently, the lithium battery body moves upward. This facilitates quick and easy removal of the lithium battery, avoiding the problem of inconvenience caused by the weight and depth of the battery compartment. By incorporating hooks and fixing rods, after the sealed casing is flipped closed, rotating the push-pull rod engages the hooks and fixing rods, enabling quick installation and fixation of the lithium battery body within the bottom shell's inner cavity. This avoids the cumbersome and inefficient installation process of traditional bolt fixing methods.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 ,in, Figure 1A schematic diagram of a preferred embodiment of the lithium battery provided by the present invention for easy installation; Figure 2 This is a cross-sectional structural diagram of the sealing shell, push-pull rod, connecting block, connecting plate, and placement plate in this invention; Figure 3 for Figure 2 The enlarged schematic diagram of part A shown below; Figure 4 for Figure 2 The enlarged schematic diagram of section B is shown below; Figure 5 for Figure 1 The enlarged schematic diagram of section C is shown below; Figure 6 This is a schematic diagram of the push-pull rod, annular block, positioning groove, positioning rod, first compression spring, and hook in this invention.

[0025] An easy-to-install lithium battery includes: a bottom shell 1; a placement plate 2, which is slidably disposed in the lower part of the inner cavity of the bottom shell 1; a lithium battery body 3, which is movably mounted on the upper surface of the placement plate 2; a sealing shell 4, which is rotatably disposed at the rear part of the upper surface of the bottom shell 1; a connecting plate 5, which is slidably mounted on the rear part of the upper surface of the bottom shell 1, and the bottom of the connecting plate 5 extends into the inner cavity of the bottom shell 1, the bottom of the connecting plate 5 is fixedly connected to the rear side wall of the placement plate 2, and the shape of the connecting plate 5 is adapted to the inner cavity shape of the sealing shell 4; a connecting block 6, which is slidably mounted in the lower part of the inner cavity of the sealing shell 4, and the bottom of the connecting block 6 is rotatably connected to the upper part of the connecting plate 5; and a push-pull rod 7, which is movably mounted in the middle of the upper surface of the connecting block 6 through a bearing, and the top end of the push-pull rod 7 extends to the outside of the inner cavity of the sealing shell 4.

[0026] An annular block 8 is movably mounted on the upper part of the inner cavity of the sealing shell 4 via a bearing. The outer surface of the push-pull rod 7 is slidably connected to the inner wall of the annular block 8. A hook 9 is fixedly mounted on the outer surface of the annular block 8. The front end of the hook 9 extends to the outside of the inner cavity of the sealing shell 4. A groove is opened at the corresponding position on the front part of the upper surface of the bottom shell 1. A fixing rod 10 is fixedly mounted in the inner cavity of the groove. The hook 9 is movably connected to the fixing rod 10. After the sealing shell 4 is flipped and closed, the hook 9 is engaged with the fixing rod 10 by rotating the push-pull rod 7, which facilitates the installation and fixation of the lithium battery and improves the installation efficiency.

[0027] A set of positioning grooves 11 are equidistantly provided on the lower circumferential part of the outer surface of the annular block 8. A positioning rod 12 is slidably installed on the upper rear side of the inner cavity of the sealing shell 4. The positioning rod 12 is movably connected to the positioning grooves 11, which can prevent the push-pull rod 7 from rotating arbitrarily.

[0028] The outer surface of the positioning rod 12 is movably fitted with a first compression spring 13. The two ends of the first compression spring 13 are fixedly connected to the outer surface of the positioning rod 12 and the inner wall of the sealing shell 4, respectively. Under the elastic force of the first compression spring 13, the positioning rod 12 can be made to contact the positioning groove 11.

[0029] Two assembly slots are symmetrically formed on the left and right sides of the upper surface of the bottom shell 1. An assembly rod is fixedly installed in the inner cavity of the assembly slot. A slider 14 is slidably sleeved on the outer surface of the assembly rod. The outer wall of the slider 14 is slidably connected to the inner wall of the assembly slot. A second compression spring 18 is movably sleeved on the outer surface of the assembly rod. The two ends of the second compression spring 18 are fixedly connected to the front side wall of the slider 14 and the inner wall of the assembly slot, respectively. A support rod 15 is rotatably installed on the upper part of the slider 14. The upper part of the support rod 15 is rotatably connected to the lower part of the front side wall of the sealing shell 4, which improves the stability of the sealing shell 4 after it is flipped open.

[0030] Two sets of limiting grooves 16 are symmetrically opened in the inner cavity of the sealing shell 4. A set of limiting rods 17 is fixedly installed on the lower part of the outer surface of the push-pull rod 7. The outer surface of the limiting rod 17 is movably connected to the inner wall of the limiting groove 16. When the push-pull rod 7 is rotated clockwise to make the limiting rod 17 enter the inner cavity of the corresponding limiting groove 16, the outer surface of the limiting rod 17 contacts the inner wall of the limiting groove 16, which can limit the push-pull rod 7 and prevent it from moving in the vertical direction.

[0031] In use, with the sealed shell 4 flipped open, the second compression spring 18 causes the slider 14 to move, which in turn moves the support rod 15. The support rod 15 supports the flipped-open sealed shell 4, improving its stability and facilitating the removal of the lithium battery. The vertically moving push-pull rod 7 moves the connecting block 6, which in turn moves the connecting plate 5. The connecting plate 5 moves the placement plate 2, which in turn moves the lithium battery body 3 vertically, facilitating the removal of the lithium battery. Simultaneously, rotating the push-pull rod 7 causes the limiting rod 17 to engage with the corresponding limiting groove. The combination of 16 and 17 can vertically limit and fix the push-pull rod 7. When the sealing shell 4 is flipped and closed, the push-pull rod 7 is rotated to drive the ring block 8 to rotate, thereby driving the hook 9 to rotate and engage with the fixing rod 10. This allows for the quick installation and fixation of the lithium battery body 3 in the inner cavity of the bottom shell 1. The positioning rod 12 engages with the positioning groove 11 under the elastic force of the first compression spring 13, which can limit the push-pull rod 7 and prevent it from rotating randomly. This improves the stability of the engagement between the limiting rod 17 and the limiting groove 16, and also improves the stability of the engagement between the hook 9 and the fixing rod 10.

[0032] This invention features a sealed shell 4 that flips open, allowing the push-pull rod 7 to move upwards, which in turn moves the connecting block 6, causing the connecting plate 5 to move vertically. This, in turn, moves the lithium battery body 3 upwards, facilitating quick and easy removal of the lithium battery. This avoids the problem of operators finding it inconvenient to remove the lithium battery from the battery compartment due to its weight and depth. By incorporating a hook 9 and a fixing rod 10, when the sealed shell 4 is flipped closed, rotating the push-pull rod 7 engages the hook 9 with the fixing rod 10, enabling quick installation and fixation of the lithium battery body 3 within the inner cavity of the bottom shell 1. This avoids the cumbersome operation steps and low installation efficiency associated with traditional bolt fixing methods.
