Description

Technical Field

[0001] This utility model relates to the field of lithium battery installation technology, and more specifically, to a novel lithium battery assembly box. Background Technology

[0002] Lithium-ion electric vehicles, also known as lithium battery electric vehicles, have become the ideal power source for the next generation of electric vehicles in recent years due to their excellent performance. Lithium-ion batteries are characterized by their light weight, large energy storage, high power, and zero pollution, and their application in various fields is becoming increasingly widespread. Significant progress has been made in their research and production. The use of lithium-ion batteries as a power source in electric vehicles has become a new trend in the development of electric vehicles. The advanced technology of lithium-ion batteries and their application in emerging key markets have stimulated a global research and development boom. Therefore, lithium-ion batteries are bound to occupy an important position in the fields of electric vehicles and new energy.

[0003] In existing technologies, heat dissipation holes are typically installed on the protective box of lithium battery packs to dissipate the heat generated during operation. However, long-term idle lithium battery packs are prone to dust entering the protective box and affecting the battery pack. At the same time, the protective box of lithium battery packs usually contains springs. When the protective box of lithium battery packs experiences large-amplitude vibrations, the springs absorb the vibrations to reduce the vibration amplitude of the lithium battery and achieve the purpose of protecting the lithium battery. However, idle lithium battery packs are in a static state and do not have the need for vibration damping. However, the idle lithium batteries will still exert pressure on the springs for a long time, causing the springs to shorten and become non-rebound due to prolonged pressure. This results in a rapid decrease in the elastic coefficient of the springs and a reduction in the lifespan of the springs. In view of this, we propose a new type of lithium battery pack box. Utility Model Content

[0004] The purpose of this invention is to provide a novel lithium battery assembly box to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, one objective of this utility model is to provide a novel lithium battery assembly box, comprising a box body with openings at both the top and bottom. Several baffles are horizontally arranged in a rotating array near the top of the box body. One end of each baffle extends to the outside of the box body and is equipped with a rotating mechanism. The rotating mechanism drives the baffles to rotate synchronously. When the baffles rotate to a horizontal position, they block the opening at the top of the box body. A shelf is slidably arranged inside the box body. The lithium battery is installed between the shelf and the baffles, and is mounted on the shelf. Several through slots are formed on the shelf. The inner walls of the two outermost through slots are provided with slots, and corresponding sleeves are provided inside the outermost through slots. A displacement mechanism is provided on the sleeves. When the rotating mechanism drives the baffles to rotate, the rotating mechanism drives the displacement mechanism to rotate, causing the two displacement mechanisms to move the two sleeves closer together, allowing the sleeves to insert into the corresponding slots. A shock-absorbing mechanism and a cooling mechanism are provided on the lower surface of the shelf.

[0006] As a further improvement to this technical solution, the baffle is rotatably mounted inside the housing via a rotating shaft, with one end of the baffle shaft extending to the outside of the housing. The rotating mechanism includes a worm gear coaxially fixedly connected to the baffle shaft. A worm is rotatably mounted on one side of the housing, with several worm gears meshing with the worm. A U-shaped rotating frame is fixedly connected to the side wall of the worm, and the rotating frame is connected to the worm near both ends of the worm.

[0007] As a further improvement to this technical solution, the displacement mechanism includes a lead screw rotatably disposed inside the housing, a ferrule threadedly connected to the lead screw, a square sleeve fixedly connected to the inner wall of the housing, and the ferrule slidably disposed inside the square sleeve.

[0008] As a further improvement to this technical solution, one end of the lead screw extends to the outside of the housing and is coaxially fixedly connected to a driven wheel, and a driving wheel is coaxially fixedly connected to the worm gear, and a transmission belt is drivingly connected to the driving wheel and the driven wheel.

[0009] As a further improvement to this technical solution, the shock absorption mechanism includes four connecting rods hinged to the lower surface of the shelf. The connecting rods are inclined, and a slider is hinged to the other end of the connecting rod. A damping rod is fixedly connected to one end of the slider, and the other end of the damping rod is fixedly installed on the inner wall of the box. A spring sleeved on the damping rod is provided between the slider and the inner wall of the box. A reinforcing plate is slidably provided on the lower surface of the slider, and the reinforcing plate is fixedly installed on the inner wall of the box.

[0010] As a further improvement to this technical solution, the air-cooling mechanism includes a motor fixedly installed at the center of the lower surface of the shelf, a fan coaxially fixedly connected to the output shaft of the motor, two air inlet slots opened on both sides of the box near the bottom, and a dust filter screen fixedly installed inside the box, the dust filter screen being positioned between the air inlet slots and the fan.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This new type of lithium battery assembly box allows the owner to rotate several rotating plates synchronously to a horizontal position by rotating the worm gear through the rotating frame when the lithium battery is idle for a long time. This seals the opening at the top of the box, preventing dust from falling into the box and improving the safety of the lithium battery. At the same time, the rotating worm gear drives the ferrule to rotate through the displacement mechanism, so that one end of the ferrule is inserted into the slot. The ferrule and the slot work together to restrict the vertical movement of the storage plate, preventing the spring from shortening due to long-term compression and extending the service life of the spring.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figures 1-6 As shown, one of the objectives of this embodiment is to provide a novel lithium battery assembly box, including a box 1 with openings at both the top and bottom. Several baffles 2 are horizontally arranged and rotatably rotated near the top of the box 1. A shelf 4 is slidably arranged inside the box 1. The lithium battery is installed between the shelf 4 and the baffles 2, and is mounted on the shelf 4. The shelf 4 has several through slots 41. A cooling mechanism 5 is provided on the lower surface of the shelf 4. The cooling mechanism 5 is used to cool the lithium battery. The structure of the cooling mechanism 5 is detailed below, referring to... Figure 4 The air-cooling mechanism 5 includes a motor 51 fixedly installed at the center of the lower surface of the shelf 4. A fan 52 is coaxially fixedly connected to the output shaft of the motor 51. Two air inlet slots 11 are opened on both sides of the housing 1 near the bottom. A dust filter 12 is fixedly installed inside the housing 1, between the air inlet slots 11 and the fan 52. The motor 51 and the lithium battery are electrically connected to the control equipment on the electric vehicle. When the lithium battery is working, the output shaft of the motor 51 drives the fan 52 to rotate. The fan 52 draws air into the housing 1 through the air inlet slots 11. When the airflow passes through the mesh of the dust filter 12, the dust filter 12 filters out the dust in the air. The airflow after filtering out the dust blows onto the surface of the lithium battery through the through slot 41. Then the airflow flows out of the housing 1 through the gap between the baffles 2. During this process, the airflow carries the heat dissipated by the lithium battery to the outside of the housing 1 through the heat exchange between the airflow and the surface of the lithium battery, thereby enhancing the heat dissipation performance of the lithium battery.

[0031] When an electric vehicle travels on rough roads, the lithium battery vibrates. If the vibration amplitude is too large, the internal components of the lithium battery are easily damaged by mutual collision. To solve this problem, a shock-absorbing mechanism 6 is provided on the lower surface of the shelf 4. The shock-absorbing mechanism 6 can reduce the vibration amplitude of the lithium battery when the housing 1 vibrates in the vertical direction. The structure of the shock-absorbing mechanism 6 is described in detail below, referring to... Figure 4 and Figure 6 The shock absorption mechanism 6 includes four connecting rods 61 hinged to the lower surface of the shelf 4. The connecting rods 61 are inclined, and a slider 62 is hinged to the other end of each connecting rod 61. A damping rod 63 is fixedly connected to one end of the slider 62, and the other end of the damping rod 63 is fixedly mounted on the inner wall of the housing 1. The slider 62 can only move horizontally along the axis of the damping rod 63. A spring 64 is sleeved on the damping rod 63 between the slider 62 and the inner wall of the housing 1. A reinforcing plate 65 is slidably mounted on the lower surface of the slider 62. The reinforcing plate 65 is fixedly mounted on the inner wall of the housing 1. The reinforcing plate 65 provides support and guidance for the slider 62, thus strengthening the slider 62. The connection strength between the damping rod 63 and the inner wall of the housing 1 is such that when the housing 1 vibrates vertically, the vibration is transmitted to the shelf 4 and the lithium battery, causing the shelf 4 to slide up and down inside the housing 1. The moving shelf 4 drives one end of the connecting rod 61 to move, causing the other end of the connecting rod 61 to drive the slider 62 to slide along the upper surface of the reinforcing plate 65. The moving slider 62 causes the damping rod 63 and the spring 64 to undergo elastic deformation, so that the damping rod 63 and the spring 64 absorb part of the vibration, thereby reducing the vibration amplitude of the shelf 4 and the lithium battery and improving the safety of the lithium battery during the electric vehicle's journey.

[0032] When the lithium battery is idle for a long time, the motor 51 is off, and there is no airflow inside the housing 1 to escape through the gaps between the baffles 2. Therefore, dust falling under gravity can easily fall into the housing 1 through the gaps between the baffles 2, causing a large amount of dust to adhere to the surface of the lithium battery and increasing the possibility of lithium battery failure. To solve this problem, a rotating mechanism 3 is provided at one end of several baffles 2 to the outside of the housing 1. The rotating mechanism 3 is used to drive several baffles 2 to rotate synchronously. The structure of the rotating mechanism 3 is detailed below, refer to Figure 3The baffle 2 is rotatably mounted inside the housing 1 via a rotating shaft. One end of the rotating shaft extends to the outside of the housing 1. The rotating mechanism 3 includes a worm gear 31 coaxially fixedly connected to the rotating shaft of the baffle 2. A worm 32 is rotatably mounted on one side of the housing 1. Several worm gears 31 mesh with the worm 32. A U-shaped rotating frame 33 is fixedly connected to the side wall of the worm 32. The rotating frame 33 is connected to the worm 32 near both ends of the worm 32. When the electric vehicle is expected to be idle for a long period of time, the owner of the electric vehicle will move the rotating frame 33 to the inside of the housing 1. The rotating frame 33 drives the worm gear 32 to rotate. Through the meshing transmission between the worm gear 32 and the worm wheel 31, the worm wheel 31 rotates. The rotating worm wheel 31 drives the baffle 2 to rotate synchronously. When the rotating frame 33 is rotated to the lowest position, the baffle 2 rotates to a horizontal state. Several baffles 2 block the opening at the top of the housing 1, preventing dust from entering the housing 1 through the opening at the top of the housing 1. This prevents a large amount of dust from adhering to the surface of the lithium battery after long-term inactivity, thus improving the safety of the lithium battery.

[0033] Meanwhile, when the electric vehicle is expected to be idle for a long period of time, the lithium battery does not need to be damped because it is in a static state. However, the lithium battery and the shelf 4 will still put pressure on the spring 64, causing the spring 64 to shorten without rebound due to prolonged compression. This results in a rapid decrease in the elastic coefficient of the spring 64 and reduces its service life. To solve this problem, slots 42 are provided on the inner walls of the two outermost through slots 41, and a sleeve 8 corresponding to the slot 42 is provided inside the outermost through slot 41. The sleeve 8 is provided with a displacement mechanism 7. When the rotating mechanism 3 drives the baffle 2 to rotate, the rotating mechanism 3 drives the displacement mechanism 7 to rotate, so that the two displacement mechanisms 7 drive the two sleeves 8 to move closer to each other and insert the sleeves 8 into the corresponding slots 42. At this time, the sleeves 8 and the slots 42 cooperate to restrict the vertical movement of the shelf 4, so that the spring 64 is always in a stable compressed state. The shelf 4 will not push the slider 62 close to the inner wall of the housing 1 through the connecting rod 61, so that the spring 64 will not shorten without rebound, thereby extending the service life of the spring 64.

[0034] The structure of displacement mechanism 7 is detailed below, referring to... Figure 4 and Figure 5The displacement mechanism 7 includes a lead screw 71 rotatably disposed inside the housing 1, a sleeve 8 threadedly connected to the lead screw 71, a square sleeve 72 fixedly connected to the inner wall of the housing 1, the sleeve 8 slidably disposed inside the square sleeve 72, one end of the lead screw 71 extending to the outside of the housing 1 and coaxially fixedly connected to a driven wheel 73, a driving wheel 34 coaxially fixedly connected to the worm gear 32, and a transmission belt 74 drivingly connecting the driving wheel 34 and the driven wheel 73. When the vehicle owner rotates the worm gear 32 through the rotating frame 33, the worm gear 32 drives the driving wheel 34 to rotate, the driving wheel 34 drives the driven wheel 73 to rotate through the transmission belt 74, and the rotating driven wheel 73 drives the lead screw 71 to rotate. Through the threaded connection between the lead screw 71 and the sleeve 8, the sleeve 8 is moved along the inner wall of the square sleeve 72 close to the center of the housing 1. By inserting one end of the sleeve 8 into the inside of the slot 42, the sleeve 8 and the slot 42 cooperate to restrict the vertical movement of the shelf 4 to protect the spring 64.
