Description

Technical Field

[0001] The utility model relates to the technical field of mining lamps, in particular to a solid-state battery for mining lamps. Background Art

[0002] A miner's lamp is short for mining lamps or industrial and mining lamps. Currently, miner's lamps are primarily used in coal mines, where high temperatures, humidity, and gas levels are high. They typically consist of a lamp holder, cable, and battery. These batteries are typically lead-acid or lithium-ion batteries, which are large and have low capacity. Furthermore, due to the unique operating environment of miner's lamps, these batteries must be waterproof and spark-resistant. If moisture enters the miner's lamp battery, it can cause a short circuit, leading to heating and fire in the entire device. This can cause explosions in the high-gas environment of coal mines. To prevent these accidents, existing battery cases are often used to protect the battery from external contact. For example, the new miner's lamp battery case described in Patent No. 201320710130.5 isolates the battery, but such cases cannot be worn directly, making them extremely inconvenient to use.

[0003] Solid-state batteries use solid electrolytes as separators between the positive and negative electrodes, eliminating the flammable and explosive drawbacks of liquid electrolyte lithium batteries, greatly improving battery safety, and are a good alternative to energy storage batteries and power batteries. They are small in size and large in capacity, but most solid-state batteries currently use single-layer packaging, which has poor restraint capabilities. When used in mines, the packaging shell is easily swollen due to friction with the body (clothing), which can cause separation between the electrodes, seriously affecting the use effect.

[0015] The present invention will be further described below in conjunction with all the accompanying drawings. The preferred embodiments of the present invention are as follows: Figure 1 To the attached Figure 4The solid-state battery for a mining lamp described in this embodiment includes a rear shell 1, a front cover 2, and a battery body 3, wherein the front side opening of the rear shell 1 forms a battery entrance, a "7"-shaped buckle plate 4 is provided on the rear side of the rear shell 1, a rear partition 5 is vertically fixed to the middle of the inner cavity of the rear shell 1, and a battery chamber is reserved in the rear shell 1 in front of the rear partition 5. Side buffer layers 6 are provided on the cavity walls on both sides of the battery chamber. The battery body 3 is installed in the battery chamber, and the two sides of the battery body 3 are in conflict with the side buffer layers 6, and the rear side of the battery body 3 is in conflict with the rear partition 5. A front cover 2 is provided at the battery entrance, and a front buffer layer 7 is provided on the inner wall of the front cover 2. The front buffer layer 7 is in conflict with the front side of the battery body 3. An inverted "T"-shaped pole foot contact piece 8 is provided on the top of the battery chamber, and a wire connecting piece 9 is provided on the top of the rear shell 1. The wire connecting piece 9 is connected to the pole foot contact piece 8.

[0016] The top of the rear shell 1 of the battery chamber is provided with a through pole foot groove, in which a metal pole foot tube is fixed, the lower part of the wire connecting piece 9 is inserted into the upper part of the metal pole foot tube, and the vertical wall of the pole foot contact piece 8 is inserted into the lower part of the metal pole foot tube. A pole piece bolt is engaged on the rear shell 1, and the pole piece bolt contacts the top of the horizontal wall of the pole foot contact piece 8, and the bottom of the horizontal wall of the pole foot contact piece 8 contacts the pole foot at the top of the battery body 3. The rear shell 1 is in the shape of a flat box, and the battery rear partition 5 is fixed to the rear shell 1 in the shape of a fence or a grid. A heat dissipation chamber is reserved in the rear shell 1 on the rear side of the rear partition 5, and heat dissipation holes 10 that pass through the rear shell 1 on both sides of the heat dissipation chamber are provided. The heat dissipation chamber is filled with a honeycomb-shaped anti-static nylon plate.

[0017] With the above solution, the front cover is connected to the rear housing via conventional clips or bolts. The battery body consists of a positive electrode structure, solid electrolyte, and negative electrode structure enclosed in a housing. The housing is installed in the battery compartment. The top of the battery body is provided with battery pins that connect to the positive and negative electrode structures respectively. The side buffer layer is made of EPE pearl cotton.

[0018] The solid-state battery's packaging shell (battery body) is implanted into the battery chamber. The sides and front of the packaging shell are buffered by corresponding buffer layers, and the front and back are limited by the front cover and rear partition. The pole foot contact piece is pressed on the electrode and then locked by the pole piece bolt to make the pole foot contact and connect with the pole foot of the battery body. At the same time, the battery body is also locked in the battery chamber. This prevents the pole foot contact piece from separating from the pole foot of the battery body, and improves the contact performance.

[0019] The vertical walls of the wire connecting piece and the pole foot contact piece are always in contact with the inner wall of the metal pole foot tube. When in use, the buckle plate is buckled on the user's belt / waist belt or safety belt, and the rear side of the rear shell is in contact with the user's clothing;

[0020] Connect the headlamp cable to the wire connector to power the headlamp. After the rear housing adopts a heat dissipation chamber, the heat of the solid-state battery can be conducted to the heat dissipation chamber and dissipated through the heat dissipation holes. At the same time, it also prevents the solid-state battery from direct contact with the outside world, and the solid-state battery will no longer wear out. It also prevents the heat of the battery from being directly transferred to the user's body (on clothing) to prevent overheating.

[0021] The use of lateral heat dissipation also prevents body sweat from directly contacting the packaging shell (battery body) through clothing. Even if it enters, it will be blocked by the anti-static nylon plate. The use of double-layer shell protection can make the solid-state battery more stable.

[0022] The use of a rear shell also prevents the generation of static electricity. Even if static electricity is generated due to contact with clothing, it is absorbed by the anti-static nylon plate. After adopting this solution, the solid-state battery is effectively prevented from contacting the outside world and can be worn directly. It has a reasonable structure and good use effect.

[0023] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any changes made based on the shape and principle of the present invention should be included in the scope of protection of the present invention.
