Background technology:
At present, electric motor car is at China's very universal, it is owing to charging conveniently, simple to operate, instead of the status of bicycle people, but electric motor car is because needs electric power is as power, that is exactly must according to battery in car, and existing battery is mounted in battery case, battery case is fixed in the battery case on vehicle frame, it is generally fixedly connected with, so just make car when vibrating, its battery case also can vibrate, and due to battery case be that Hard link is in vehicle frame, it does not have other buffer unit, of long duration, on the use of battery, there is impact, the connecting line welded in battery is easily made to depart from, electric motor car cannot be opened, impact uses, and existing battery case does not have any ventilating structure, when electric motor car uses and charges, capital makes the temperature in battery case rise violently, when deployed, old battery long afterwards can be too high and produce the potential safety hazards such as blast due to temperature.
Summary of the invention:
The object of the invention is to overcome the deficiencies in the prior art, a kind of battery of electric vehicle displacement structure with buffering effect is provided, it makes battery case have buffering effect when electric motor car runs, improve useful life, simultaneously, battery case has air vent hole, the heat in battery case can be made to carry out certain discharge, improve fail safe.
The scheme that the present invention solve the technical problem is:
A kind of battery of electric vehicle displacement structure with buffering effect, comprise vehicle frame, the middle part of described vehicle frame has battery standing groove, sleeve in battery standing groove is also fixed with battery case containment vessel, the sidewall of battery case containment vessel has multiple through hole that is spirally connected, the sidewall of battery standing groove also has multiple through hole, through hole and the through hole one_to_one corresponding that is spirally connected, bulb plunger is screwed onto and is spirally connected in through hole, battery case is placed in battery case containment vessel, the middle part lateral wall of battery case has circular orientation portion, the steel ball of bulb plunger is nested in the shrinkage pool that circular orientation portion has, the bottom surface of battery case containment vessel is fixed with multiple buffer spring, cushion pad is placed on buffer spring, battery case is pressed against on cushion pad, the top of battery case containment vessel has been bolted to connection protection cap, in the middle part of the bottom surface of protection cap, there is elastic cord breaker, elastic cord breaker is pressed against on the end face of battery case.
The bottom sidewall of described battery case has air vent hole, circular orientation portion has vertical air vent hole, the upper portion side wall of battery case containment vessel has ventilation through hole, battery standing groove has the outer vent communicated with ventilation through hole.
The end face of the top board clad battery box containment vessel of described battery case, the edge of the top board of battery case has vertical through wires hole, and the upper portion side wall of battery case has side through wires hole.
Described outer vent is the truncated cone-shaped through hole that outer diameter is large.
The bottom surface of described cushion pad has multiple body, and buffer spring sleeve is in body.
Outstanding effect of the present invention is:
Compared with prior art, it makes battery case have buffering effect when electric motor car runs, and improves useful life, meanwhile, battery case has air vent hole, the heat in battery case can be made to carry out certain discharge, improves fail safe.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is partial top view of the present invention.
Embodiment:
Embodiment, see as shown in Fig. 1 to 2, a kind of battery of electric vehicle displacement structure with buffering effect, comprise vehicle frame 10, the middle part of described vehicle frame 10 has battery standing groove 11, sleeve in battery standing groove 11 is also fixed with battery case containment vessel 20, the sidewall of battery case containment vessel 20 has multiple through hole 21 that is spirally connected, the sidewall of battery standing groove 11 also has multiple through hole 12, through hole 12 and through hole 21 one_to_one corresponding that is spirally connected, bulb plunger 22 is screwed onto and is spirally connected in through hole 21, battery case 30 is placed in battery case containment vessel 20, the middle part lateral wall of battery case 30 has circular orientation portion 31, the steel ball of bulb plunger 22 is nested in the shrinkage pool 32 that circular orientation portion 31 has, the bottom surface of battery case containment vessel 20 is fixed with multiple buffer spring 23, cushion pad 24 is placed on buffer spring 23, battery case 30 is pressed against on cushion pad 24, the top of battery case containment vessel 20 has been bolted to connection protection cap 25, in the middle part of the bottom surface of protection cap 25, there is elastic cord breaker 26, elastic cord breaker 26 is pressed against on the end face of battery case 30.
Further; the bottom sidewall of described battery case 30 has air vent hole 33; circular orientation portion 31 has vertical air vent hole 34, the upper portion side wall of battery case containment vessel 20 has ventilation through hole 35, battery standing groove 11 has the outer vent 13 communicated with ventilation through hole 35.
Further, the end face of the top board clad battery box containment vessel 20 of described battery case 30, the edge of the top board of battery case 30 has vertical through wires hole 36, and the upper portion side wall of battery case 30 has side through wires hole 37.
Further, described outer vent 13 is the truncated cone-shaped through hole that outer diameter is large.
Further, the bottom surface of described cushion pad 24 has multiple body 27, and buffer spring 23 sleeve is in body 27.
Its, by bulb plunger 22 locating batteries box 30, to moving radially of battery case 30, there is certain buffering effect simultaneously, when electric motor car is vibrated, ensure can not damaging of battery case 30, internal connection line can not depart from, and cushion pad 24, buffer spring 23 and elastic cord breaker 26 all ensure that the vibration-isolating effect of battery case 30 in the vertical direction.
And the heat discharge in battery case 30 can be lowered the temperature by air vent hole 33, vertical through hole 34, ventilation through hole 35, outer vent 13; and the edge of the top board of battery case 30 has vertical through wires hole 36; the upper portion side wall of battery case 30 has side through wires hole 37; this makes power line can be passed by side through wires hole 37 and vertical through wires hole 36; and through the jack on protection cap 25; it is passed by side through wires hole 37; outside water droplet can be placed directly instill in battery case 30, there is certain waterproof effect.
Finally; above execution mode is only for illustration of the present invention; and be not limitation of the present invention; the those of ordinary skill of relevant technical field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification, therefore all equivalent technical schemes also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
