Description

Technical Field

[0001] This utility model relates to the field of battery protection technology, and in particular to a drop-proof and explosion-proof protection device for built-in lithium batteries in lamps. Background Technology

[0002] Lighting fixtures can illuminate the outside world, and portable lighting fixtures allow for easy repositioning of the light source, ensuring that people are not visually distracted while watching or learning. Portable lighting fixtures are typically powered by lithium batteries.

[0003] However, existing lighting fixtures offer poor protection against lithium batteries, as they are typically directly attached to the power board via adhesive. Therefore, when the fixture is accidentally dropped to the ground, the lithium battery experiences a significant instantaneous impact, potentially leading to an explosion. This increases safety risks for users and makes the fixture inconvenient to use. To address these issues, we propose a built-in lithium battery drop-proof and explosion-proof protection device for lighting fixtures. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies mentioned in the background section by proposing a drop-proof and explosion-proof protection device for built-in lithium batteries in lamps.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The lamp has a built-in lithium battery drop and explosion protection device, including a lamp housing with an opening at the bottom and a handle base at the bottom. The lithium battery body is located above the handle base and extends into the lamp housing. A lower battery box is located below the lithium battery body, and an upper battery box is located at the top of the lithium battery body. The lower and upper battery boxes cover and protect the lithium battery body. It can protect the entire lithium battery body, thereby preventing the lithium battery body from shifting and thus preventing short circuits in the circuit connections. At the same time, it can buffer the lithium battery body to prevent it from exploding due to impact.

[0006] Preferably, a charging block is provided inside the handle base, and a buckle plug cable is provided on the bottom side of the lithium battery body, and the buckle plug cable is electrically connected to the charging block; This allows for separation between the lithium battery body and the charging block, thus preventing the lithium battery body from exploding due to an impact from the charging block.

[0007] Preferably, both the lower battery box and the upper battery box have a U-shaped cross-section, and the lower battery box has a groove on its side. It can improve the cable routing of the buckle plug.

[0008] Preferably, buffer pads are provided on both sides of the lower battery box, and the buffer pads are in contact with the inner wall of the lamp housing; This allows for further cushioning on both sides of the lower battery box, resulting in better stability of the lower battery box for the lithium battery body.

[0009] Preferably, the top and both sides of the upper battery box are provided with supporting rubber pads, and the supporting rubber pads are in contact with the inner wall of the lamp housing on three sides. It can cushion the four sides of the upper battery box, thereby cushioning the lithium battery body and reducing the impact force on the lithium battery body.

[0010] Preferably, a buffer airbag is provided at the top of the inner wall of the upper battery box, and a support plate is provided at the bottom of the buffer airbag, with the support plate fitting against the top of the lithium battery body. The buffer airbags and support plates can provide cushioning and protection for the main body of the lithium battery, thereby further protecting the main body of the lithium battery.

[0011] Preferably, the top edge of the buffer airbag is provided with an airbag inflation port, and the top of the airbag inflation port extends through the upper battery box to the outside. The airbag can be inflated, which improves the cushioning effect of the airbag and support plate on the lithium battery body.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model can isolate the lithium battery body from the charging block through the lower battery box. At the same time, the lower battery box and the upper battery box can support and protect the lithium battery body, preventing the lithium battery body from shifting after being impacted, thereby improving the stability of the lithium battery body and reducing the probability of explosion.

[0013] 2. This utility model can protect and cushion the lower and upper battery boxes through buffer pads and support pads, thereby preventing the lower and upper battery boxes from shifting and further improving the stability of the lithium battery body. At the same time, the buffer airbag cushions the lithium battery body through the support plate, further reducing the impact force on the lithium battery body after it is dropped, thereby further reducing the possibility of the lithium battery body exploding.

[0016] 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.

[0017] Reference Figure 1-4 The lamp shown has a built-in lithium battery drop and explosion protection device. A handle base 2 is fixedly installed on the bottom of the lamp housing 1 by bolts. A charging block 4 is set inside the upper part of the handle base 2. Then, a lower battery box 6 is fixedly installed on the top of the charging block 4. The lower battery box 6 has a U-shaped cross-section and an opening on one side. The lithium battery body 3 is placed in the groove at the top of the lower battery box 6. A buckle plug cable 5 is fixedly installed on the bottom side of the lithium battery body 3. The buckle plug cable 5 is electrically connected to the charging block 4 through the groove on the side of the lower battery box 6. After the handle base 2 is placed inside the charging compartment, the lithium battery body 3 can be charged normally through the charging block 4 and the buckle plug cable 5. Both sides of the lower battery box 6 are provided with buffer pads 7, so that the buffer pads 7 are in contact with the inner walls of the lamp housing 1. At the same time, the lithium battery body 3 extends from the bottom of the lamp housing 1 and is installed inside the lamp housing 1.

[0018] For a detailed description of the upper battery box 8 in this embodiment, please refer to [link / reference]. Figure 3 and Figure 4An upper battery box 8 is provided above the lithium battery body 3. The upper battery box 8 has a U-shaped cross-section, so that the upper battery box 8 fits onto the outside of the lithium battery body 3. Then, support pads 9 are attached to the left, right and top sides of the upper battery box 8. The support pads 9 are in contact with the inner wall of the lamp housing 1 on three sides, which can cushion the lithium battery body 3. At the same time, a cushioning airbag 11 is fixedly installed at the top of the inner wall of the upper battery box 8. A support plate 10 is fixedly installed at the bottom of the cushioning airbag 11, so that the support plate 10 is in contact with the top of the lithium battery body 3. An airbag inflation port 12 is fixedly installed on the top side of the cushioning airbag 11, so that the top of the airbag inflation port 12 extends through the end of the upper battery box 8 to the outside. Personnel can inflate the cushioning airbag 11 through the air pump and the airbag inflation port 12, so that the cushioning airbag 11 further cushions the lithium battery body 3 through the support plate 10.

[0019] Working principle: When the lamp housing 1 is dropped, the upper battery box 8 and the lower battery box 6 can protect the lithium battery body 3 as a whole, preventing the lithium battery body 3 from tilting or shifting. At the same time, the buffer pad 7 and the support pad 9 can protect the lower battery box 6 and the upper battery box 8 as a whole, preventing the lower battery box 6 and the upper battery box 8 from shifting. They can also provide cushioning, thereby preventing the lithium battery body 3 from exploding due to the large impact force after falling to the ground.

[0020] Personnel can inject gas into the interior of the buffer airbag 11 through the airbag inflation port 12. Then, the buffer airbag 11 supports and buffers the top of the lithium battery body 3 through the support plate 10. Thus, when the lithium battery body 3 is impacted, it can be buffered by the buffer airbag 11, further reducing the impact force on the lithium battery body 3, thereby further preventing the lithium battery body 3 from exploding after falling to the ground.
