Engine

Abstract

The invention discloses an engine. The engine includes an engine body, a lithium battery applied to the engine is installed on the engine body, and a core shaft of the lithium battery is parallel to an air cylinder shaft of the engine body; the core shaft of a lithium battery unit arranged to be parallel to the air cylinder shaft of the engine body, so that relatively large stress which is generated due to vibration and is in the direction of a main vibration shaft is parallel to positive and negative electrode layers, which is conducive to reducing deformation, caused by vibration stress, of the positive and negative electrode layers, it is ensured that the positive and negative electrode layers have high adhesive force to active substances, adverse effects of vibration on the lithium battery are reduced, and it is ensured that the lithium battery can be normally used for a long term; an electrode contact face between the lithium battery and the engine body is vertical to the core shaft, which is conducive to decontamination through vibration and ensuring smooth conduction of the contact face, it is ensured that contact electrodes are effectively and electrically connected, the contact resistance is reduced, and it is ensured that the starting voltage to the engine body is stable.

Description

technical field [0001] The invention relates to a power device, in particular to an engine. Background technique [0002] The engine is a machine that converts the chemical energy of fuel into mechanical energy output. Most of the starting power used for starting the engine is a lead-acid battery, and the lead-acid battery is large in size, heavy in weight, low in energy density, easy to self-discharge and unfavorable There are many disadvantages in storage, etc.; therefore, there is a lithium battery as the starting power of the engine. Compared with the traditional lead-acid battery, under the same capacity parameters, the overall size is reduced, the weight is also reduced, and the battery life is improved. service life; in the prior art, the lithium battery is fastened and fixed on the engine body through the mounting slots, and the contact electrodes are respectively set on the engine body and the lithium battery. When the lithium battery is installed on the engine body...

[0002] The engine is a machine that converts the chemical energy of fuel into mechanical energy output. Most of the starting power used for starting the engine is a lead-acid battery, and the lead-acid battery is large in size, heavy in weight, low in energy density, easy to self-discharge and unfavorable There are many disadvantages in storage, etc.; therefore, there is a lithium battery as the starting power of the engine. Compared with the traditional lead-acid battery, under the same capacity parameters, the overall size is reduced, the weight is also reduced, and the battery life is improved. service life; in the prior art, the lithium battery is fastened and fixed on the engine body through the mounting slots, and the contact electrodes are respectively set on the engine body and the lithium battery. When the lithium battery is installed on the engine body, the engine body It is electrically connected with the lithium battery to improve installation efficiency; and because the lithium battery is fixedly installed on the engine body for a long time, and the engine will vibrate violently during use, it is easy to cause adverse effects on the lithium battery, such as a decrease in battery capacity, The output voltage is reduced or the life is shortened, which seriously affects the normal use of lithium batteries
