Description

Portable battery box

Technical Field

The utility model relates to a battery case, especially a portable battery case for holding large capacity storage battery.

Background

A battery box in the prior art is a box body structure for storing and protecting an internal battery. The application scenarios are generally divided into movable and non-movable cases. The use scene of the immovable battery box is relatively fixed, the structural design of the immovable battery box does not need to consider various complex use conditions, and only needs to be adapted to the use environment of the immovable battery box, such as a battery used by an automobile, the immovable battery box basically has no external battery box and only uses a simple external fixing frame; and as for a battery cell used by an electric bicycle, the shape of a battery box of the battery cell is generally directly designed to be consistent with the shape of a battery mounting position of the electric bicycle, and the battery box is integrally packaged with the internal battery cell, so that a user is prohibited from manually disassembling the battery box.

Along with the improvement of living standard of people, scenes of using batteries outdoors are more and more, and the requirement that a large-capacity storage battery can be moved by movable power requirements is more and more. This requirement has two features, the first is undoubtedly mobility, and the second is to have multiple types of sockets in order to meet various different use requirements.

In response to this need, there are two types of products on the market:

1. battery case and inside storage battery encapsulation are integrative, and this kind of product packaging structure is inseparable, and inside storage battery is fixed firm, walks line reasonable in design, rocks less in the transportation removes the in-process, has avoided the vibration, has rocked storage battery damage or the interface pine scheduling problem that probably causes. However, the packaging structure cannot be disassembled, so that the internal battery can hardly be maintained once the internal battery is aged or the circuit problem occurs, and the use cost is high.

2. The battery case is separated from the internal battery, and a user can configure and replace the internal battery by himself, so that the use cost is low. However, the storage battery is required to be installed by a user, the storage battery and various wiring harnesses in the reserved internal space are mixed together, and a corresponding fixing structure is not needed. In the moving and using processes, the storage battery is easy to damage or the interface is easy to loosen due to vibration and shaking.

Meanwhile, the same problem exists in both types of products, namely the design of the external interface is in short consideration. In both products, the external interface is simply arranged on the outer wall of the battery box, and various connectors inserted into the external interface directly protrude out of the battery box. The portable battery case is because the in service behavior is complicated, often can appear the condition that removes when pegging graft on the external interface and connecting, and the joint very easily receives the collision at the removal in-process, leads to connecting or external interface harm, even because the collision takes place the short circuit, causes the damage of inside storage battery. In some camping situations, the plug protruding from the battery compartment may be bumped for various reasons even when the battery compartment is stationary.

Disclosure of Invention

In order to solve the problem, the utility model provides a use cost is low, and can play certain guard action's portable battery case to plug under the grafting state.

In order to reach above-mentioned purpose, the utility model discloses a portable battery case, including shell and upper cover, the shell be the box structure of no top cap, the inside accommodation space that holds the storage battery that is equipped with of shell, the upper cover setting on shell upper portion, the upper cover on be equipped with power output/input interface, power output/input interface set up on the interface surface of indent in upper cover side, the both sides of interface surface be equipped with to the bellied protection bead in the upper cover outside. The structure is characterized in that the protective convex ribs on the upper cover form an integrally concave interface surface, so that the convex protective convex ribs resist most of impacts on the side surface and the front surface, and the electric power output/input interface or a joint on the electric power output/input interface is prevented from being damaged by external force.

In order to effectively separate the storage battery storage space and the wiring space, a battery separator is arranged between the upper cover and the shell, a wiring hole is formed in the battery separator, and the wiring space is formed between the battery separator and the upper bottom surface of the upper cover. Through the design of battery separator, can all restrict the circuit part of battery case in the line space of walking, only expose main positive and negative wiring outside through crossing the line hole to simple effectual guide user's wiring. Meanwhile, the battery separator can further play a certain limiting role on the storage battery arranged in the shell, so that the storage battery is prevented from moving up and down.

For the relative position of further fixed battery baffle and upper cover, battery baffle include baffle body and set up at baffle body elasticity limit all around, the plane at elasticity limit place and the plane at baffle body place become the obtuse angle setting, be equipped with the breach of stepping down between two adjacent elasticity limits, and at least one elasticity edge is equipped with the location notch, the upper cover be equipped with step down the concave arris of location of breach cooperation upwards sunken lid, and be equipped with on the inside wall of upper cover with the protruding muscle of location notch complex location. Through the setting of the breach of stepping down and location notch, can effectually restrict the cooperation of battery baffle in the upper cover, and the setting on elasticity limit then can guarantee to leave certain elastic buffer when the battery baffle pushes down the fixing to the storage battery, avoids the vibration rigidity of box body on transmitting the storage battery.

In order to facilitate the fixing and the separation of the shell and the upper cover, the outer side wall of the shell is provided with a fastener, and the shell and the upper cover are fixed in a matching way through the fastener.

In order to facilitate the movement of the battery box and simplify the structure of the clamping part, the outer side wall of the shell is provided with a handle, the handle is provided with a pin shaft hole, and the clamping part is connected with the pin shaft hole in a matched mode through a rotating pin shaft.

The utility model discloses a portable battery case through the interface position of reasonable design upper cover and upper cover, has formed the interface face of indent to utilize the protection bead of its both sides evagination, protected the interface and pegged graft the joint in the various uses on the interface, avoided the damage of unexpected collision butt joint and interface, the effectual life who prolongs the battery case. On the other hand, the battery separator is arranged in the battery box, the storage space and the wiring space of the battery are separated, and the battery box is prevented from moving up and down in the battery box while reasonable wiring and wiring of a user are guided. To sum up, this kind of portable battery case has structural design rationally, and is not fragile, and the storage battery is changed conveniently, long service life, and low in use cost's characteristics.
