Description

Technical Field

[0001] This utility model relates to the field of battery protection technology, and in particular to a battery assembly with a protective mechanism. Background Technology

[0002] A storage battery is a device that can convert and store chemical energy and electrical energy. It consists of positive and negative electrodes, electrolyte, and separator. When charging, it converts electrical energy into chemical energy for storage, and when discharging, it converts chemical energy into electrical energy for output. It is widely used in many fields such as automobile starting, emergency power supply, and energy storage system, providing continuous and stable power support for various electrical equipment or serving as a backup power source to ensure power supply. However, due to the special nature of storage batteries, they generally need to be protected during use.

[0003] In existing technologies, battery packs are typically placed in protective enclosures to protect the batteries and provide a layer of protection for the outside of the batteries. However, since the batteries are in close contact with the inner wall of the protective enclosure, if the outside of the enclosure is impacted, especially by a sharp object, causing the enclosure to break, the batteries that are in close contact with it will inevitably be damaged. Therefore, a battery assembly with a protective mechanism has been designed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a battery assembly with a protective mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A battery assembly with a protective mechanism includes a battery protective box. Linkage rods are fixedly connected to both ends of the inner side of the battery protective box near the bottom. A push plate is fixedly connected between four of the linkage rods. A battery is disposed on the top of the push plate, and metal contacts are disposed at both ends of the top of the battery. Two guide rods are fixedly connected between the two ends of the inner bottom of the battery protective box. A T-shaped limiting plate is slidably fitted onto the circumferential surface of the two guide rods on the same side. Both ends of the bottom of the two T-shaped limiting plates have openings adapted to the guide rods. A bidirectional lead screw is rotatably connected between the two ends of the inner bottom of the battery protective box, and both ends of the bidirectional lead screw are threaded through the bottom of the adjacent T-shaped limiting plates. Lead screw nuts adapted to the bidirectional lead screw are fixedly fitted onto the bottom of the two T-shaped limiting plates. A first buffer pad is fixedly connected to the side of the two adjacent T-shaped limiting plates. Multiple first heat dissipation holes are provided on the T-shaped limiting plates and the first buffer pad on the same side. Ventilation holes are provided on both sides of the battery protective box.

[0007] As a further embodiment of this utility model, one end of the bidirectional lead screw passes through the battery protection box and is fixedly connected to a handwheel. By rotating the handwheel, the bidirectional lead screw is driven to rotate, causing the two T-shaped limiting plates to move closer to each other or further apart. One end of the battery protection box is provided with a round hole that matches the bidirectional lead screw. A limiting wheel is fixedly fitted on the outside of the battery protection box, and multiple slots are provided on the outer circumference of the limiting wheel.

[0008] As a further embodiment of this utility model, a side plate is fixedly connected to one end of the battery protection box near the limiting wheel. Two sliding rods are slidably sleeved on the side plate. Two round holes adapted to the sliding rods are opened on the side plate. The same T-shaped locking block is fixedly connected to one end of the two sliding rods near the limiting wheel. The same limiting plate is fixedly connected to the other end of the two sliding rods. A spring is sleeved on both sliding rods between the T-shaped locking block and the side plate. The T-shaped locking block is adapted to the limiting wheel. The rotation of the limiting wheel can be restricted by the T-shaped locking block, thereby preventing the T-shaped limiting plate and the limiting rod from loosening.

[0009] As a further embodiment of this utility model, two limiting rods are fixedly connected between the two sides of the bottom inside the battery protection box. The same L-shaped limiting plate is slidably sleeved on the same end of the two limiting rods. The bottom ends of the two L-shaped limiting plates are provided with round holes that are adapted to the L-shaped limiting plates. The bottom ends of the two limiting rods are provided with oblique holes.

[0010] As a further embodiment of this utility model, an L-shaped plate is fixedly connected to the bottom of each of the two T-shaped limiting plates, and a sliding rod is fixedly connected to one end of the bottom of each L-shaped plate. Each sliding rod is slidably connected in adjacent oblique holes.

[0011] As a further embodiment of this utility model, a second buffer pad is fixedly connected to one side of each of the two L-shaped limiting plates that are close to each other. Multiple second heat dissipation holes are provided on the L-shaped limiting plate and the second buffer pad on the same side. The second buffer pad and the first buffer pad are provided to avoid damage to the battery surface.

[0012] As a further embodiment of this utility model, the top of the battery protective box is rotatably connected to a cover plate, and both ends of the top of the cover plate are provided with strip-shaped holes adapted to the metal contacts.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model employs a bidirectional lead screw, a T-shaped limiting plate, a first buffer pad, an L-shaped limiting plate, oblique holes, and a second buffer pad. After the battery is positioned inside the battery protection box, the T-shaped limiting plate and limiting rod limit its circumference, maintaining a certain distance between the battery and each side of the battery protection box, preventing wobbling. This ensures that the battery will not be damaged even if the battery protection box is impacted or broken. Furthermore, the T-shaped limiting plate and limiting rod enhance interaction, preventing damage from impacts. This effectively solves the problems mentioned in the background art, achieving effective resistance to external impacts and vibrations, preventing battery casing breakage and cell displacement, reducing short-circuit risk, ensuring battery integrity and safety, and extending service life.

[0015] This utility model, through the setting of limiting wheels, T-shaped blocks, springs, and sliding rods, restricts the rotation of the bidirectional lead screw, so that the T-shaped limiting plate and limiting rod will not loosen on their own over time during use, thus improving stability.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1-5 A battery assembly with a protective mechanism includes a battery protective box 1. Connecting rods 601 are fixedly connected to both ends of the inner side of the battery protective box 1 near the bottom. A push plate 6 is fixedly connected between the four connecting rods 601. A battery 5 is mounted on the top of the push plate 6. Metal contacts 501 are provided at both ends of the top of the battery 5. Two guide rods 7 are fixedly connected between the two ends of the bottom of the inner side of the battery protective box 1. A T-shaped limiting plate 8 is slidably fitted onto the circumferential surface of the two guide rods 7 on the same side. The bottom ends of the two T-shaped limiting plates 8 are each provided with openings that fit the guide rods 7. The two T-shaped limit plates 8 are rotatably connected by the same bidirectional lead screw 3, and both ends of the bidirectional lead screw 3 are threaded through the bottom of the adjacent T-shaped limit plates 8. The bottom of the two T-shaped limit plates 8 is fixedly fitted with lead screw nuts that are compatible with the bidirectional lead screw 3. The two T-shaped limit plates 8 are fixedly connected to the adjacent side of the two T-shaped limit plates 8. Multiple first heat dissipation holes 801 are opened on the T-shaped limit plates 8 and the first buffer pads 802 on the same side. The first heat dissipation holes 801 facilitate the heat dissipation of the battery 5, so that the heat of the battery 5 can be dissipated in time when it is working. Ventilation holes 101 are opened on both sides of the battery protection box 1.

[0025] In this embodiment, one end of the bidirectional lead screw 3 passes through the battery protection box 1 and is fixedly connected to a handwheel 301. One end of the battery protection box 1 is provided with a round hole that matches the bidirectional lead screw 3. A limiting wheel 302 is fixedly sleeved on the outside of the battery protection box 1. Multiple slots are provided on the outer circumference of the limiting wheel 302.

[0026] In this embodiment, a side plate 4 is fixedly connected to one end of the battery protection box 1 near the limiting wheel 302. Two slide rods 401 are slidably sleeved on the side plate 4. Two round holes adapted to the slide rods 401 are opened on the side plate 4. The same T-shaped locking block 403 is fixedly connected to one end of the two slide rods 401 near the limiting wheel 302. The same limiting plate 404 is fixedly connected to the other end of the two slide rods 401. Springs 402 are sleeved on both slide rods 401 between the T-shaped locking block 403 and the side plate 4. The T-shaped locking block 403 is adapted to the limiting wheel 302. Through the setting of the T-shaped locking block 403, springs 402 and slide rods 401, the bidirectional lead screw 3 can be limited to prevent it from loosening during use and causing the battery 5 to shake.

[0027] In this embodiment, two limiting rods 9 are fixedly connected between the two sides of the bottom inside the battery protection box 1. The same L-shaped limiting plate 901 is slidably sleeved on the same end of the two limiting rods 9. The bottom ends of the two L-shaped limiting plates 901 are provided with round holes that are adapted to the L-shaped limiting plates 901. The bottom ends of the two limiting rods 9 are provided with oblique holes 902. The oblique holes 902 cooperate with the sliding rod at the bottom of the L-shaped plate 803, so that when the two T-shaped limiting plates 8 approach each other, the two limiting rods 9 also approach each other.

[0028] In this embodiment, an L-shaped plate 803 is fixedly connected to the bottom of each of the two T-shaped limiting plates 8, and a sliding rod is fixedly connected to one end of the bottom of each L-shaped plate 803. Each sliding rod is slidably connected in the adjacent inclined hole 902.

[0029] In this embodiment, a second buffer pad 903 is fixedly connected to one side of the two L-shaped limiting plates 901 that are close to each other, and multiple second heat dissipation holes 904 are opened on the L-shaped limiting plate 901 and the second buffer pad 903 on the same side.

[0030] In this embodiment, a cover plate 2 is rotatably connected to the top of the battery protection box 1. Both ends of the top of the cover plate 2 are provided with strip holes 201 that are adapted to the metal contacts 501. The setting of the strip holes 201 does not affect the operation of the battery 5 and facilitates the output of electrical energy.

[0031] Working principle: When using this component, after opening the cover 2 and placing the battery 5, the T-shaped locking block 403 is moved, causing it to separate from the limiting wheel 302. The spring 402 is compressed. Then, the handwheel 301 is rotated, causing the bidirectional lead screw 3 to rotate, which in turn causes the two T-shaped limiting plates 8 to move closer together, thus limiting both ends of the battery 5. Simultaneously, as the two T-shaped limiting plates 8 move relative to each other, the L-shaped plate 803 and the sliding rod allow the sliding rod to slide in the inclined hole 902, causing the two L-shaped limiting plates 901 to move closer together, thus limiting both sides of the battery 5. This ensures that the battery 5 is limited on all four sides. Battery 5 is located in the middle of battery protection box 1. Loosening the T-shaped locking block 403 allows it to engage with the limiting wheel 302, preventing the bidirectional lead screw 3 from rotating on its own. This ensures that the T-shaped limiting plate 8 and the limiting rod 9 will not loosen. At the same time, the first buffer pad 802 and the second buffer pad 903 can provide some protection for battery 5, preventing damage to the surface of battery 5. By limiting battery 5 through the T-shaped limiting plate 8 and the limiting rod 9, when the outside of battery protection box 1 is impacted, the battery 5 will not be damaged due to the large distance between it and the edge of battery protection box 1, thus improving the service life of battery 5. In addition, the movable design of the T-shaped limiting plate 8 and the limiting rod 9 facilitates the placement and removal of battery 5.
