Description

General type battery compartment and have electrical apparatus of battery compartment

Technical Field

The utility model relates to a battery compartment especially relates to a be applicable to the battery compartment of 1.5v zinc-manganese battery and 3v lithium-manganese battery simultaneously and can select the electrical apparatus of using 1.5v zinc-manganese battery or 3v lithium-manganese battery in same battery compartment.

Background

The mobile electric appliances such as electric appliance remote controllers, electric toys, cameras, sensing equipment and the like are usually powered by batteries, so that the mobile electric appliances are provided with a battery compartment for placing the batteries and leading out the batteries, the battery compartment is usually only suitable for batteries with the same specification, the autonomy of a consumer to select which battery to adopt after purchasing the electric appliance is limited, and the consumer can only select the brand and variety of the batteries within the range of the batteries with the same size and the same or similar voltage. For example, the AA battery can only select AA size, alkaline batteries and carbon batteries which are all 1.5v or approximate 1.5 nominal batteries, and AA batteries with nominal voltage approximate to 1.5v, such as nickel-hydrogen rechargeable batteries, nickel-cadmium rechargeable batteries and lithium-iron batteries, which are commonly used.

The patent with publication number CN 204966554U discloses a universal battery bin, which can be used for placing AA batteries and non-standard square lithium batteries in the same bin body, and the two batteries are placed in the same battery position and share the same set of input and output positive and negative pole pieces. However, the battery compartment has the following problems: firstly, the non-standard square lithium battery is limited in specification and can only be produced by a specific manufacturer, and due to no standardization, the non-standard square lithium battery is difficult to realize mass production and cannot be obtained from other channels, so that the selection and purchase of consumers are greatly limited; secondly, the non-standard square lithium battery has higher cost; thirdly, the AA battery and the non-standard square lithium battery share the same set of input and output positive and negative pole pieces, and when the AA battery generates a liquid leakage phenomenon to corrode the pole pieces, the non-standard square lithium battery cannot be used.

A general type dual chamber battery compartment device is disclosed in patent publication No. CN 205846075U. The U-shaped double-head buckle assembly is arranged in the battery bin, batteries of different models can be clamped conveniently, and the negative electrode of the battery chamber is connected with springs of different lengths, so that batteries of AA and AAA can be used in a mixed mode.

Although carbon zinc batteries, alkaline batteries and the like belong to zinc-manganese series dry battery products, the batteries are relatively cheap, have more sales points and are convenient to purchase, but have the problems of unstable working current performance, short service life, and particularly easy leakage to cause damage to electric appliances, and the like, and consumers often have damage to electric appliances such as remote controllers and electronic clocks due to battery leakage when using the electric appliances for a long time, and the batteries are often required to be connected in series for use due to the voltage of only 1.5v, so that the portability, the reliability and the leakage risk of the batteries are increased. The lithium manganese battery has the advantages of long service life (more than 10 years), stable current, small volume, light weight and the like compared with dry battery products such as alkaline batteries and the like, although the price is higher, and the lithium manganese battery can be singly used in many cases because the nominal voltage reaches 3v, and the number of the lithium manganese battery is reduced by half compared with that of the dry battery even if a plurality of the lithium manganese batteries are connected in series. More importantly, the problem that the leakage damages the electric appliance is solved, and the battery pack is particularly suitable for high-end products such as safes and the like with high requirements on the reliability of the battery. The zinc-manganese and lithium-manganese batteries are used as cylindrical primary batteries, have high product standardization degree, and are convenient for mass production of battery manufacturers, so that consumers can purchase the batteries conveniently. However, the zinc-manganese battery and the lithium-manganese battery are not only different in size, but also cannot be used universally and interchanged by adopting a conventional method due to different nominal voltages. The nominal voltage of the zinc-manganese battery is 1.5V, while the nominal voltage of the lithium-manganese battery is 3V, so that no universal battery compartment for alkaline and lithium-manganese batteries exists in the electric appliance in the market at present. For example, patent No. CN 205846075U can solve the problem of placing batteries of different types, but cannot solve the problem of different output voltages caused by the nominal voltages of the batteries, and needs to be provided with another voltage circuit to adapt to the nominal voltage.
