Description

Technical Field

[0001] This invention belongs to the field of electronic design and is a 12V-18 type battery compartment structure, which is a battery installation structure that can be used for the installation of 12V-18 type batteries in the "Military Battery Series Catalog - General Battery". Background Technology

[0002] Based on power and continuous operating time requirements, a certain product needs to be powered by a 12V-18 type battery. Since the product is cylindrical, the battery must be inserted from one end. Furthermore, the 12V-18 type battery has a size of 254... -0 1×79 -0 0.5 ×42 -0 0.5 The battery (mm) is relatively long, has large dimensional tolerances, and its shape changes with ambient temperature. Traditional methods of electrode installation are prone to reverse connection, are time-consuming, and have low efficiency. The battery compartment needs a suitable structure and dimensional tolerances to guide the accurate alignment and insertion of the positive and negative terminals of the battery with the battery compartment interface. Since the 12V-18 battery is a newly developed product in China, there is no matching battery compartment on the market. Therefore, in view of the above, a 12V-18 battery compartment structure was designed. This battery compartment structure not only allows for convenient and quick installation and removal of the 12V-18 battery, but can also be installed inside a certain type of product {product outer diameter φ98mm}, and has excellent heat dissipation performance and reliability. Summary of the Invention

[0003] The purpose of this invention is to develop a convenient 12V-18 battery compartment structure with appropriate dimensional tolerances. The system ensures accurate positioning of the connector after the battery is inserted into the 254mm long stroke, allowing for easy power connection once the battery is installed. The pull hook facilitates battery removal, and the rear locking mechanism provides reliable fixation. The hollow structure at the top and bottom of the battery facilitates heat dissipation during operation. The battery holder interface and battery holder are machined separately, improving manufacturability and effectively solving the problem of easy electrode reversal. This enhances work efficiency and reliability, reducing the installation time from 15 minutes to 2 minutes. Attached Figure Description

[0004] This invention has two accompanying drawings.

[0005] Figure 1 This is a schematic diagram showing the installation direction of the 12V-18 type battery for the product.

[0006] Figure 2 This is a schematic diagram of the 12V-18 battery compartment structure. Detailed Implementation

[0007] This invention provides a 12V-18 type battery compartment structure. For example... Figure 1In the schematic diagram shown, after the battery is installed, the tail of the product rotates upward and closes. The tubular shape of a certain type of product and the rectangular shape of the battery compartment structure form a structure for air circulation on both the top and bottom, which facilitates heat dissipation of the battery.

[0008] The battery compartment structure consists of a battery holder (1), a battery holder interface (2), a wire interface (3), a hook (4), and a hook bracket (5), see below. Figure 2 The battery holder (1) is made of aluminum alloy. To ensure dimensional tolerances, it is machined as a single piece and includes a support ring, a fixing thread, and an upper guide block. The support ring prevents the battery holder from deforming, and the upper and lower cutouts facilitate finger gripping of the battery. The battery compartment is connected to a certain type of product via a fixing thread and matching screws. To prevent the front end of the battery from tilting upwards during installation, the rounded corners of the upper guide block guide the battery downwards, ultimately fitting the wire interface (3). The upper guide block is small in size and does not affect the processing of other structures. The wire interface (3) has large connectors at both the front and rear ends. The battery holder interface (2) is located below... The end is designed with a notch, through which the wire interface (3) can be screwed and installed on the battery socket interface (2), and then the whole assembly is installed on the battery socket (1). The wire interface (3) and the battery interface are closely matched in size, and the positive and negative terminals can be accurately connected during installation. However, if the battery is affected by extreme temperature, it is not easy to pull out during disassembly. Therefore, a hook (4) is designed and fixed on the battery socket (1) with a hook bracket (5) and screws. When installing the battery, the hook (4) moves forward. When it is difficult to remove the battery, the fingers hook the hook (4) and pull backward, and the battery is pulled out with the hook (4).
